[Q] Tips to extend battery life? Anyone?

Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!

I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).

Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!
Chris R.

I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience

Thanks for the tip!

Thanks for the reply! Also thanks for the tip regarding JuiceDefender! What a great app! will give it some more time and report results back here.
Thanks again!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.

juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well

JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........

here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps

Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Look here- try stopping the DRM service and see if that helps your battery life with D107

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?

I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.

Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.

Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.

Do you have juice defender installed?

Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.

That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)

Nexus 6P - Bad SOT

Hey guys, I'm very new to XDA but I really hope someone can help me out. I'm a nexus fan and its just the best but I bought the nexus 6P thinking that I'm going to get around 6 Hours SOT considering I used to get around 4 with my N5 with the same level of usage. I want to know what I'm doing wrong or if I'm overlooking something.
Let me tell you about my phone and how I use it.
I have Elemental X + Pure nexus installed
Elemental x settings are on Ghost Pepper and I put CPU governmer on ' ondemand '
• I don't have Facebook and Messenger installed (These two were some SERIOUSS battery hoggers )
• I use google chrome push notifications as a replacement
• I use snapchat but not very excessively
• Turned off all gestures as i never used them
• Adaptive display is off
• Ambient display is off
• Notification Lights are off
• GOOGLE automatically syncs everything at anytime but other than that i manually sync whatsapp
• Location is always off except at rare times
• I use bluetooth to connect to my car to play music for an hour daily.
• Brightness is at 30-60% for 3/5th the day, 2/5th of the time it's lower than 30%.
• LTE is on for aboutt 4-5 hours a day and the rest is on WIFI.
Furthermore, I use my laptop more than my phone so I'm constantly picking up my phone and am not allowing it to fall into deep sleep for a good amount of time except at night or when im playing some serious CSGO; I noticed that its during the screen off time where I'm losing so much battery.
Now after reading all of this, do you still think I deserve to get that much screen on time?
Is there some setting I have missed out or is it the kernel + rom combination, I am really frustrated. This phone is magical but the battery is just so disappointing, I want at least 5 hours on screen time (I just barely reach 4 hours SOT)
Oh and let me further explain how the battery dies. Usually I'll be browsing facebook or 9gag and using snapchat and lets say its at 90%, it wont budge for 10 minutes or even more regardless of how heavily I use it. But the moment I turn the screen off and turn it back on, woooshh I'll lose 1%, and when I start using it again, another percent drops instantly. This is just seriously irritating and I have no clue as to what I need to do.
Thank you for any help!

No one I've ever read of gets 6 hours of screen time on this device. Between 4.5-5+ is pretty typical.

Playing music while the screen is off will have a pretty big impact on sot, especially if it's playing via the phones speakers. I know that has a big impact on my sot. There are some screenshots on here of 6 hours sot, but I suspect they set the screen timeout very high while leaving the device inactive. 4 hours is the average sot on this device from my experience.

GhostPepper is meant to run on interactive governor not ondemand. Disable TouchBoost under CPU in EXKM.
As for the rest I can't comment because you use the phone differently than mine.

I came to understand that phones are different from each other. Some have 5-8 hours of SOT and some have 3-5 hours SOT. Usage is different from each person and phone.

I would agree with several of the others that SoT is more typically 4-5 hours...I use my phone pretty heavily so I'm probably toward the shorter end of that, but even with a somewhat degraded battery (70% according to accubattery) I can still get 3 or at least close. Now granted I was only getting 1-1.5 but I went through and wiped my phone, heavily limiting the number of apps I had installed (I had a ton), and reducing the number of Google apps and services (now, etc.) that I used. Other than that just a couple minor kernel tweaks (hawktail6p profile, disable touchboost, disable zram, etc. not even sure on that last one lol)...anyways getting much better battery afterwards.

I get 2 hours of sot. My phone is about a year-and-a-half old.
I have tried all sorts of ROMs and different kernels and every tweet you can think of to try to extend my battery life. But nothing works. I'm going to have to just get a different phone soon.

Choder...I have also had my Nexus 6P since the first week it was released. I also was getting horrible battery life and I decided to order a new battery and replace it. I can tell you that my factory battery over almost a year and 3 months, had degraded horribly.
Remember when you first got it charged it up to full, the battery percentage would read 100 percent for almost a half hour BEFORE dropping. Well, it's like that again with this new battery I ordered off of ebay. Routinely getting between 5 and 6 hours SOT. I don't use my device for games, so its browsing, youtube, checking email and messages throughout the day. Don't get a new phone...spend the 13 bucks on a new battery and save the cash.

i've seen the DIY battery replacement video on youtube. Looks difficult IMO. what did you think? Have you ever done anything like that before? really interested in trying but intimidated and don't want to bork my phone....

I am getting 2.5h SOT....any governor, any kernel, any ROM....just a bad device to buy for a good battery life.
I mean, it's frickin huge!! Of course you should expect 4h...but 2.5h cmon....I swear of God there is something wrong with Android...my phone turns off at 35% saying Power (0%) Shutting down...WTF?!?

That shutdown at 30% is a known issue. You should RMA your phone. Huawei extended the warranty at least through the end of this month.

If you find DIY intimidating you can always get a quote from a phone repair place. It would be cheaper than getting a new phone but you have to do some extreme things to get long battery life out of the 6P because the phone wasn't really made that way. Rooting, using a kernel tuned for battery savings (which will likely affect the performance of the phone) and using Naptime (which puts the phone into Doze as soon as the screen goes off) will all increase overall battery life.

It's not as difficult as it looks. Just make sure you have the proper tools. A heat gun, the hobby knife to fit between the aluminum body and the plastic screen housing.
Once you get the separation you can use a guitar pick to undo the clips around the edges of the 6p. Just take your time.

So you haven't seen all. I can use my phone and get 6 to 7h SOT (check here on XDA and you will see a lot of people achieving the same). Places where LTE is very bad combined with Google services trying to sync whatever is the biggest drainer here that can bring me down to 4h.

We'll I average 6:41 sot based on gsam averages. My phone rarely gets below 50-55% before I'm charging that night (9am-12am) the last time I was at 50% was a could days ago and was at 3:40 sot. The biggest thing I do is on any rom or kernel...
First is turn off all the sync under Google. That means contacts, calendar... Everything. No reason to let all the stuff just sync all day long. If I add a contract I go in account, Google and sync my contacts. The next thing I do is turn off all the background data syncing under data usage, cellular data usage for apps that need not sync. I leave days syncing for things like Google app, text apps browser, things your need to sync. Put location to battery saving unless I need high accuracy.
That's it, it's not rocket science, of you're still getting bad sot, your phone is likely with bad signal, not sleeping from a rouge app or maybe the battery is degraded a lot. If you're getting the shutdown issue, then RMA your phone, that's a bad bug.

In my case I was talking about sync under 'backup and reinit'. Having to switch off normal google sync would be a bit of a hassle. I use gmail (which is crap but haven't reconnected k9mail yet) and more important i use keep to share stuffs. I prefer sync over sot and I anyway reach a day.
But in my case, believe me, the root cause is bad gapps sync when having atrocious 3G (LTE little less draining) which is half of my day.
At home data connection is OK and I can get past 6h as I said. My device is only 6 months old. I have an estimated capacity of 3440mAh.

Stock QC2 Firmware - Battery tips?

Hi Friends,
Just wonder if this is normal for this phone, or you guys could give me some pointers for extending my battery life, specifically the Screen On Time?
I have:
- Stock QC2 firmware - I believe this is Nougat with the March security patch
- No Facebook installed (Disabled)
- I am on data about 8 hours a day, rest is WiFi, Bluetooth for my Watch, and NFC is off
- Generally use a black and red theme
- Doing Ad blocking with the AdClear VPN solution
- Sometimes I make conference calls of under 2 hours
- No games, no YouTube watching
With this set I can barely manage like 3 hours of SOT. Is this normal? What am I doing wrong? Any pointers? Thanks!

3 hours SOT is not normal for unrooted stock. I would suggest downloading GSam Battery Monitor and finding out what is hogging the battery. Note that you will need to manually enable the battery statistics permission with ADB for some reason, but after that it will work like normal.
The top two lines should be Android System and Kernel. If you see any non-system app in the vicinity, that is your likely culprit unless you can explain it with normal usage (for example, Firefox is at the top of the list on mine because I surf the web with it)
Alternately, if nothing odd shows up, you may have a bad battery.

The other thing you might take a look at is shutting off the Location setting that scans Wifi/Bluetooth. That is a massive battery killer

Thank you for the helpful responses guys! I'll try GSam Battery stuff... What are your SOTs BTW?
Thanks!

Also my vibration is always on, my back lit keys are always on, and a 30 second screen timeout time, if it helps? Thanks!

Finally, this is the AT&T model with all the bloat disabled.

I'm typically off charge 18 hours and on data the entire time. I do run a Exchange email app that pushes email, my SOT isn't really huge, maybe around 2-3 hours and I also have BT always on and connected to my S3 Frontier. At the end of my day, I end up with with battery around 50% ish.........
Did you recently update, or did you do a clean install? Sometimes the battery can take a few days to settle in

That's pretty amazing! Yes, clean install and updated from MM to Nougat and then the latest patch.
I've got a battery monitoring app installed now... Let's see what it unveils... I'm thinking maybe it's my settings, syncing and etc, cause I NEVER get the SOTs people report on XDA LOL, on any phone really except the Mate 9 I had...

Battery life is SO subjective. The app's installed and the person's usage habits play a massive part in battery life, and you saying that you never get what others are, speak a lot to that.
The built in optimizers in Nougat seem to do a pretty good job at putting unused battery sucking apps to sleep.

Just wonder if this is normal for this phone, or you guys could give me some pointers for extending my battery life, specifically the Screen On Time?
I have:
- Stock QC2 firmware - I believe this is Nougat with the March security patch
- No Facebook installed (Disabled)
- I am on data about 8 hours a day, rest is WiFi, Bluetooth for my Watch, and NFC is off
- Generally use a black and red theme
- Doing Ad blocking with the AdClear VPN solution
- Sometimes I make conference calls of under 2 hours
- No games, no YouTube watching
With this set I can barely manage like 3 hours of SOT. Is this normal? What am I doing wrong? Any pointers? Thanks!

I notice one thing, when i connect my Gear 2 by bluetooth battery on phone less about 10-15% less. With out watch and no FB and FB messenger, NFC on, most of day on data, wifi off, 5-6 hours call ( do to nature of my job) i get around 3.5 hours SOT.

Battery life is SO subjective. The app's installed and the person's usage habits play a massive part in battery life, and you saying that you never get what others are, speak a lot to that.
The built in optimizers in Nougat seem to do a pretty good job at putting unused battery sucking apps to sleep.

I agree bud, so I think my usage pattern must be horrible, cause from the earliest Androids like Droid Incredible to Axon 7 and S7 Edge and others, I never get what people mention. And some of their claimed usage is ridiculous, they say they play games all day, LTE, Videos and still get like 5 hours or etc... Boggles my mind. My biggest battery hog I suspect is my VPN based AdGuard, maybe the vibration, but compared to gaming and etc, they sound so insignificant.

Yeah, that's more like my usage. Without my Watch, this may be the case. I don't use NFC. Thanks for sharing your experiences.

3 hours SOT is not normal for unrooted stock. I would suggest downloading GSam Battery Monitor and finding out what is hogging the battery. Note that you will need to manually enable the battery statistics permission with ADB for some reason, but after that it will work like normal.
The top two lines should be Android System and Kernel. If you see any non-system app in the vicinity, that is your likely culprit unless you can explain it with normal usage (for example, Firefox is at the top of the list on mine because I surf the web with it)
Alternately, if nothing odd shows up, you may have a bad battery.

This is a actually normal for USA SAMSUNG battery which is why no1 should get Galaxy S7 on USA carriers battery is even 100 maH smaller at 3500. Battery is always crap usa versions. And I am stuck in them nougat is bad for battery nothing you can do but downgrade to Android 6.0.1 with Odin. Best battery I can upload a vid for proof att Samsung S7 edge battery sucks and so will all USA carriers s8 never buying Samsung again GG. Switch phones best option iPhones have best battery but I hate them. I'd go for a phone with biggest mAh in specs and read reviews for battery. If downgrading doesn't work sorry for all Samsung lovers who read this it's just fact if you actually compare USA version to international. Battery on international is 92 ish hours not even close on USA version +1 sorry for my rant. Second best option I went to zero lemon and got a battery charging case that was like 10000 something maH and I never loose battery because I keep case on entire time makes phone weigh 4 pounds tho

Thank you for sharing your thoughts, bud, I think I would agree, this must be reality. An update for me, seems like getting rid of the VPN based Adblocker has helped battery. Last night, I finally got 4 hours SOT, but that was with the VPN app. Trying without it all day, let's see how it goes.
BTW, hands down, the best battery I have ever seen in the US is on the Huawei Mate 9, even on Nougat. The HUGE battery helps, but legitimately, I was getting 7 hours of SOT.
Thanks guys!

Got the attached SOT after turning off the VPN based ad blocker and using it as needed, rather than on the whole time... Is this closer to normal? ?

I only get 3-4hrs SOT but it is connected to my huawei watch and music is playing when it connects to my bluetooth fm transmitter in my car. I also usually have it plugged in while driving. The best battery life SOT I've seen is on the moto z play. My sister has that phone and she got almost 9hrs SOT. Usually gets at least 7. Someone got over 10.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Sony Xperia XZ1 Compact before depleting the battery.
Then, drop a comment if you have anything to add!

Battery life on this phone is amazing.
Since it has the same 2700mAh battery as its bigger brother, it can easily last 2 days of average usage.
I'm currently typing this at 7pm, and my phone is at 71% battery, while I've been up since 8:30am

Checked the battery monitor on hidden menu and it states 2800mah (my currently battery % is 80)
how much you guys have?

2820mAh according to the service menu battery test, not bad.

Are you guys using Stamina mode? I am new to the Xperia phones and the XZ1 Compact is a first for me. I came to it from a Google Pixel because I wanted a smaller phone for better one-handed use and better battery life. So far, I'm not seeing much increase over the Pixel with my usual usage. I have only had it for a few days and have been ending the day around 30-35%. Phone idle and Google Play Services seem to utilize the most battery and my typical screen time in a day is around 1:45-2:00 hours.

I set stamina to kick in at 15%
I haven't reached that point yet, right now I have 25% remaining and already have 6.5 h of sot. I didn't do anything too demanding, but half the day the signal was rather bad, so in the end I gotta say this thing is a beast.

Not using stamina. Didnt like the lag on screen when stamina was on. on android is pretty good now with disabling apps on background...
i usually have 5 hours screen...

Modern Stamina is completely different from the original Stamina, which was awesome. Back in the golden days, it was actually able to effectively extended battery life without sacrificing overall performance.
With the introduction of Marshmallow however, Stamina essentially "broke" - there were overlapping conflicts with MM's new Doze feature, which in theory aimed to conserve battery in ways similar to Stamina but in reality didn't quite live up to its promise.
Since Doze is baked in to the OS and pretty much here to stay, Sony decided to kill off Stamina with the first few MM firmware releases.
It was eventually resurrected, but it has never been the same again. You can say that only the name lived on, under the hood it's two entirely different things.
Now that history lesson is over, back to your question. Stamina on the XZ1 Compact is just a combination of trivial battery saving tricks that may or may not actually save a significant amount of battery life.
The description in Stamina mode details the biggest battery eating features that Stamina disables, if you don't actively use any of them during normal use, it's likely that Stamina won't be of much help in conserving battery for you.
You'll probably save more battery by dimming your screen or disabling ambient light sensor.
Ultra Stamina basically turns your smartphone into a dumbphone to squeeze as much life as possible out of the remaining battery. Unless you're away from a charger for a long time and you absolutely need to make a phone call or text or whatever before you can plug it in, don't use this mode, it's horrid.

Thanks for the brief history lesson! I did notice Stamina mode left some to be desired with scrolling, primarily. After messing around with some settings and putting the screen to a dimmer level, I seem to be getting better battery life. Perhaps it has to do with a new phone and the software and battery need to "learn" each other? As it is, the XZ1C is already longer lived than my Pixel, which typically needed to be plugged in at least once to make it through the day. Honestly, I'd take a thicker phone with larger battery. A wafer-thin phone with the latest tech is useless if the battery is dead.

I use stamina the whole time. I've found the bottom stamina preset is the best for scrolling. It's barely noticeable over non-stamina. Also, I've disabled background data and set location to GPS only. I get about 8-9hrs of SOT.

This phone is a bit unpredictable. I was pleasantly surprised by the improved battery life earlier in the week, and now it barely lasts through my usual 16 hour day before getting into the red. This past Saturday and Sunday, I had about 4 hours screen time and the phone made it through my day with 43% left in the battery. Monday I got about 3 hours screen time and finished with just over 20%, and yesterday I wrapped up with 7% and only used it for 1:45 screen time. I haven't done anything differently or installed any new apps. The reception is a little worse at my office is than at the school where I teach part-time, but I don't think that should make a 30% difference in battery life. I still get full bars WiFi and 2-3 bars LTE, where at the school LTE is usually 4-5 bars. Funny thing is, I about double my screen time at the teaching job since students don't always need me so I'm browsing on my phone. At my office, I'm usually busy and don't touch the phone much at all, but these past two days I'm practically watching the percentage drop. Today, I'm off the plug for about 2.5 hours and already down to 86% with 5 minutes screen-on time.
I'm thinking there must be some background app or process running that is killing the battery, but the app usage shows "phone idle" as the highest power drain, followed by Google Play Services. I often like to keep the more "core" apps running in the background so they can pull updates, notifications, etc. so I don't have to constantly be pushing the phone to do them manually.

I agree but still dont use this... scrolling with stamina is not that smooth like with stamin off.

Maybe I should try stamina off with background sync disabled. The scrolling is smooth, but it feels like the display refresh is only 30fps, which still bothers my eyes.

Just surfing reddit and listen to Spotify. Wifi and bt 100% on.

Wow. 2 days of standby and 10 hours of screen usage?? How did you manage that? I'm happy with just one full day when I don't have to plug in. I've already turned off most location services and updates, leaving just essentials like e-mail and weather still on. I also used to have a live wallpaper, which has now been changed to a static photo.

I have uninstalled all Google apps besides: Gmail, Calendar and Keep.
I have uninstalled all the bloat experia apps including swift key. (see thread: https://forum.xda-developers.com/xperia-xz1-compact/help/managed-to-hide-whats-app-root-t3681393)
I use a black wallpaper and also night-mode in chromium swe browser.
I have turned off 4G/LTE since it sux in Sweden. Use only 2G/3G+Wifi.
I use dns66 for Adblock.
I have no audio/video enhancements on.
I have set auto brightness to off (low light auto brightness sux on xz1c)
I use Pebble 2SE which uses BTLE (LowEnergy)

Perhaps a bit off topic, however I would like to know how is the auto brightness feature on this phone.
I have a soon-to-be-dead Z3 compact and I used Lux auto brightness on it since the stock one basically didn't do anything.

The auto brightness on this phone works well, even too well. Sometimes in certain environment, a little tilt on the phone will cause the brightness to adjust immediately. I would say it is the most sensitive auto brightness in all phones I've used this far.

Almost 3 days with 7+ hours of screen on time

Guys this phone battery is amazing! I use my smartphone for public relations so i always use whatsapp, instagram etc... I wake up around 8-9 and don't have any problems the whole day.. gps on everywhere, google apps on, data on all time, use some spotify too and don't remember what else. I wouldn't change it for anything and would suggest you to buy it. Gj SONY.

Getting 17hrs of screen on time minimum on full charge for youtube 3hrs , clash of clans 2hrs and 45-50 mins of calls per day....last 3 days with my usage
Plus Whatsapp of 1 hrs approx per day

SS or it didn't happen

I've had this phone 2 days and so far I've had 6 hours 31 minutes of screen time and I have 58 percent battery left. This is mostly YouTube, Web browsing, an hour of downloading apps from play store and a bit of emulation (ppsspp) am extremely impressed with the battery life on this phone.

Battery lasts more than 2 days at Medium Power Saving mode with moderate apps usage(no gaming but with youtube, magic fluid live wallpaper, whatsapp, browsing) and SOT approx 13+ hours in these two days. At the end of second day battery remains at 30-35%.

Has anybody here compared to the Moto G8 Power? Is the battery life even better?

Exactly how do you think a cheap SD 665 11nm chip with a 5,000mAh battery will do against a higher tier SD 730g 8nm chip with a 7,000mAh battery?
Hmmmmm ?

To come back on it, I have it since today and so far it's looking like the G8 Power has better or equal batterylife, standby drain is somehow bad on the M51, I checked all apps. Still I'll let the software settle and get through more cycles and check Gsam Battery Monitor in a couple of days again.
I honestly blame Samsung's other apps that aren't used and aren't able to be disabled or uninstalled.

Hi guys. I wanted to let you know my findings and provide some test results of galaxy m51 battery life. Firstly, I will outline what was my priority for that test. I wanted to check how long the phone can last mainly on google maps navigation with additional apps in the background. Also this test is a bit static so to speak but had no chance travelling for so many hours. That said I believe SOT was tested correctly for my planned usage. I guess in a real case scenario, I would need to do some more browsing and perhaps occasional screen switch offs during a break like filling up the fuel or stop to rest on a bicycle.
How I performed my test.
1. I did some initial installations, downloaded my apps and logged in to social apps such as FB, Spotify so they can work in the background, send notifications etc.
2. Once I completed the setup, I charged the very new phone to 100%. AccuBatter reported capacity was 6800mAh designed capacity not 7000mAh and estimated capacity 6700mAh.
3. CPU-Z reported Snapdragon 730 so I regret it is not 730G and honestly I do not know how to check with online stores as the packaging does not help with this. Also, I plan to test POCO F2 PRO 8gb ram/256gb version the same way and see how it goes since I get better hardware, but I like SD card slot on galaxy m51. Very useful when resetting the phone.
4. Set google maps navigation, lunched another app which uses GPS and LTE for maps showing speed cameras, road works or dangers which I use alongside with google maps. I also start shuffle play on Spotify to imitate streaming the music in my car or on the bike.
5. WiFi, LTE, GPS, Bluetooth, sync was enabled, blue light filter enabled.
6. Between 15-20 apps were in the background.
7. I unplugged the device from the mains.
8. Initial 15% discharge was with a WiFi connection with my router. Then switched of my router for overnight, left wifi enabled on Samsung but it had to continue downloading data over LTE such as Spotify music streaming. I also changed google map setting to day light only to avoid night backlight.
9. I went to bed? and in the morning there was still a lot of juice.
10. Around 20% discharge I took about 100 pictures most of them in burst mode to simulate a trip where you simply stop and take some snaps.
11. I stopped the test at 1% discharge and noticed no heating problem. The phone was cool during the test.
The overall SOT measured until 1% discharge was a staggering 17h 50m? Below you will find AccuBattery screenshots. At remaining 15% I had still over 2 h 42 m of use left.
This phone reminded me of good, old days of my Samsung galaxy s3 with a Zerolemon 7000mAh?
Now with my galaxy s7 deteriorating battery (current capacity just over 2300mAh) this is a great thing. For Galaxy s7 I also own a KiwiBird powerbank case of 5400mAh right from the beginning wich did its job when away from the mains, travelling etc.
I guess for a more accurate SOT, I would need to add some phone calls and browsing but even with I deduct 2h, it is still nearly 16 h of use. Like for me excellent. I also do not plan gaming.
On the downside of this phone it seems like my galaxy s7 takes a bit better picture, but it just might be my perception of selfies taken. Back camera is also just ok on a cloudy day. Ok but that is an offtopic.

I got my M51 yesterday and I am not fully sure yet about battery lifetime. I have charged it to 100% and about 8 hours and 2.5 hours secreen time later I am at about 90%.
Coming from my Moto Z Play I am not sure yet if I stay with the galaxy. The Mot Z Play with Incipio OffGrid Wireless Power Pack mod is about the same size and weight. Though provides less capacity (3300mAh phone + 2200mAh power mod) but battery lifetime still was bout 3-4 days usually.
The M51 is also getting considerably warmer during use.
I noticed also the Samsung battery saver with medium settings can reduce the CPU clock to max out at 70% which is handy. Not sure if there is any undervolting, underclocking tools as I think I would be perfectly fine with less performance - actually I was able to reach insane battery life on my old Galaxy P1000 with TricksterMod and custom undervolting back in the days.
I still believe better lifetime with the M51 would be possible bz reducing CPU clock and also with better screen brightness control. I noticed many times already that the M51 screen was too bright for me and having to reduce the slider to "minimum" position or very close to it. Also I noticed that the screen brightness slider is not linear at all. So on the last notch on the left side the screen really starts to dim properly while to the right there isn't much change. Also I like still to use automatic screen brightness adjustments but found the automatic adjustment often moves the brightness too high.
Also a possibility to limit the used screen area (e.g. display black bar on bottom/top) would save energy on the AMOLED screen while still providing more than enough screen space.
EDIT: One-Handed mode sort of provides this feature, but not exactly what I was looking for (like cinema-bars on top and bottom and no prominent "one-handed-mode" title.
I will continue to use the M51 for a couple of charges and decide if I am going to trade it again. The phone itself is performing well, supporting VoLTE WiFi calling but seems to lack carrier aggregation for no apparent reason. I strongly dislike the slippery, fingerprint-attracting, cheap-looking plastic backside of it.
I also hate that everywhere you tap it tries to sign up to a Samsung account. Also replaced the launcher with Nova launcher.

Below is the answer to almost all above useless posts
Battery life tests - GSMArena.com
Why I say useless ?
Simply. SOT will be completely different when you read ebooks compared when you watch movies or browse Internet.
Gsmarena does standarised comparison
I am fan of long life battery phones. I used "king" Lenovo P2 for over 2 years. M51 is better.

I'm at the fourth cycle of charge.. and got 15 hrs so far.. have done a heavy idb debloating
maby it will increase over more charging cycles?

i m getting about 20h sot normal usage
facebook lite, browser , youtube , aliexpress and playing alphalt extreme 30 min
wifi and dark mode on
brightness between 10-40 %
data off
location off
this phone have a very good battery
