Overnight battery drop - Galaxy Tab 7.7 General

I am experiencing a 20% battery drop overnight consistently over last few days (can't remember what the drop was when i first got the tab). It's true that I have quite a few apps installed. But none running overnight that "actively" run in the notifications bar (like skype) - only 'push' stuff (email, whatsapp etc.)
Looked at what is causing it and it's "Android OS".... i hope it's not another Android OS "bug" like the Samsung Galaxy S2 (which luckily I didn't experience with my S2!)
What's everyone else's battery life in an idle state / overnight?

An easier way to diagnose this is to use betterbatterystats, it eliminates 99% of the guess work.

Have you tried betterbatterystats? It costs a few bucks, I think, but it has really helped me stop some battery killers. I was surprised by some apps that had wakelocks and weren't identified in the basic android battery information screen.

Will give it a go
So 20% drop overnight is not normal then?

I only charge mine every few days. I haven't noticed a huge battery drop overnight.

Your usage seems abnormally high.
I have monitored the battery usage overnight for the past week of my new tab 7.7 3G and at the same time my old tab 7 3G. The 7.7 drops on average of 3% overnight (equivalent to 0.3%/hour) while the old tab has been dropping 10% overnight (a little over 1%/hour).
I have a couple of screens full of widgets on both. Neither of them set to auto-update widgets and have all notifications off. Wifi is on for both, while the 7.7 has a sim in it and the tab 7 does not.

Mine was consuming battery like yours and I found out it was because of the Samsung email client that I've setup to get push email from google. The email apps keep giving me unable to connect gmail but in actual fact the email was push to me. I left it like that initially until I found exchange service as my to battery consumer. After removing my gmail account from the apps, everything back to normal. I think there is a big with the Samsung email client that keep trying to connect to the exchange server and sucks all the juice.

horrific battery life...help?!

Hi All
Once again thanks for watching my video and getting me tickets to MWC...but alas i have another issue. My Note has horrific battery life....practically about 8 hours.
I downloaded better battery stats and there are no major wakelocks going on...(just juice defender at 3.4% which i uninstalled anyway) ....any other ideas?
Any help would be appreciated, another Mobiler suggested i put a custom rom on...I'm just terrified of 'bricking' my phone lol
This is perfectly average battery life for stock rom with moderate to heavy usage but if on light usage you might have some issues. Here is my battery like with heavy use.
Don't pay attention to people claiming Days of battery life they are simply not using the phone.

Battery life is certainly better than that on my old HTC Desire HD. Far better.

Maybe you could post up your betterybatterystats results?
I was having the same problem. I have a lot of apps on my phone, and it was just draining while sleeping as far as I could see. My main issue was all the unwanted apps like the social and media hub popping up whenever they felt like chomping on my battery.
I finally gave in and rooted, and installed droidwall to prevent anything getting network access I do not allow, android assistant for its start up manager, and autorun to delete all 'event listeners' that cause apps to pop up when they like (and there are hundreds of these in the stock apps, I assure you).
I now have 50% more battery life, and it seems to lose a lot less while sleeping.
I installed the CPU speed set thingy (sorry, I forget the name) but I had the problem a few others seem to have because it drained the battery faster than ever while sleeping. I will try again after a few days. I screenshot the battery graph in full screen, showing the WiFi, wake & screen, every day so that I can get a good feel for historical usage and battery life.
I have an el cheapo battery (had two but lost one) for emergencies. I am buying a Samsung one instead (for a 'real' 2500 mAh), and expect to keep it on me at all times. That should take me through a day of pretty heavy usage. I also have some dangly 'add-on' chargers, but frankly a spare battery is neater, smaller and easier.
I have also bout a tablet (10.2" with 16GB) for $200. I fully expect to buy another - one for work and one for home. These will reduce my usage of the G-Note and leave it for actual use as a phone. The main problem is that I use it so damned much! I have my phone, contacts, all my To Do lists, email, audible books, textual books, surfing, games, etc all on one device. I also use it to type notes at meetings or the like using my folding BT keyboard. It does it all really well, but does not have the battery to cope!
I know there are fat batteries out there, but I do not want to spoil the beauty of my svelte Note by giving it a hunch-back!

I also use Llama to control things like BT, WiFi and network data access when away from home or office. It does help, and means I don't have to remember to toggle. I tried Juice Defender as well, but its idea of turning on the WiFi at intervals saved my battery but seemed to make my email (IMAP) never download. I need to know when emails come in so that did not work for me. I may try it again at some point and try to make it work better for me.
Uninstall Juice Defender. I found my phone battery lasted twice longer after I removed it.

I use my phone for note taking all day and into the evening! Screen and internet used for over 12 hours, constant use! (Screen on lowest setting)
After battery "settled" I get around 10 hours then pop in a second battery!
Took about 15 charging cycles though to get the 10 hours!
Anyway just saying it may take time! And a second battery is always safest

that's... actually pretty normal battery usage if you're using your phone a lot.
my note is operating pretty much 18hours a day. A full charge is all i need, and by the end of the day, i get the critical battery notification.
if your note lasted more than a day, that's great. But with the amount of workload i am expending using my note, i wouldn't be surprised if continued usage of the phone would only last 7 to 8 hours tops. or much less.
and besides, the note can last for more than 2 days, if you didn't use it at all.
thanks for all the suggestions...i'm going to give rooting it a go this evening. Will let you know how that goes.

Yeap, that seems like average battery life. If you notice (others) that his screen on time was pretty solid most of the time. That means of the nearly 6 hours on, I'd say about 4.x hours the screen was on. So that's good
I have managed to improve my Galaxy note battery life a LOT by doing the following:
- Disable Wi-Fi when not using it.
- Settings > Accounts and Sync > UN-TICK "Auto-sync".
With auto-sync disabled you have to manually open the relevent app to get the data, but for me, thats what I prefer, and it saves loads of battery life.
Used to be 8 hours or less with the above 2 enabled.
now 16 hours+ with the above 2 disabled !
Installed free version of Juice Defender 3 days ago, didn't do anything just keeping it on balanced mod and from now on I have extended normal battery life (phone, e-mails, sms, occasional internet through 3G) from 1 day to 2 days. What can I say ...
It works. When you switch into wifi, gaming or intensive document editing then nothing is going to save you, but just for having the phone in your pocket and using it as a "phone" Juice Defender delivers.
I noticed on the market that roughly half people say it is excellent and the other half is whining that it just sucks. Give it a try a decide for yourself.
Just turn auto sync off and untick "Use wireless networks" and you will be blown away by the battery life.
The last two days my battery was losing power too quickly compared to my previous weeks with my note.
So I thought it must be an app which I installed which is causing this. The only app I installed recently was Google + so it took it off and hey presto - battery life back to normal again.
You might say well it doesn't drain my battery with google+ installed but it works with mine as I tried re-installing again and it sapped the battery again.
Maybe different apps effect different roms, kernals etc...just a thought and something you could try with a recently installed app.

I can see that as an option, and I believe that all of those who report great battery life are doing much the same. My problem is that I want to be kept alerted to emails. I have tried Juice Defender, as it starts up wireless at defined intervals, but since my email is checking at other defined intervals, at appears that the email never gets through. I have to assume they never coincide.
I also like certain apps to sync, although I guess I could do that manually. Currently I turn on autosync while at home or work with Llama. Luckily the wireless and autosync toggles are in the notification dropdown as well - that is a wonderful idea.
I use the Note far too much, so (as I have probably said) I am getting a tablet. I hope that it will serve as my email notification when I am at home or work. When Llama knows I am at neither place, it can disable autosync and enable mobile data for me (which I keep off at home & work).
It is a delicate balance trying to get full desired operation and decent battery life. I am not sure it is really worth all the agro. I may just settle for a spare battery in my wallet and a dock/battery charger by my bedside. That is probably the easiest of all options! Then I can game away whenever I like without constantly checking the battery
Im using a custom rom rocket rom v21 with abyss kernel... which gives me a battery for 40 hours approx. With fair amount of usage. Sync off facebook app as it sucks a lot of battery too.

Awesome! Been looking for this feature for awhile now. Only downfall is just remembering to switch it back when i'm using Pandora
A bit off topic but I experienced a fluke on my battery life, was just watching simpsons while I had my wifi connected and only had my yahoo messenger connected probably a total of 10-15 messages in 4hrs range, for 4 hours of screen time it normally drains 50-51% only.
I almost always have the same scenario when I watch simpsons on my phone, yahoo messenger running but it the first time to drain it like this.

Galaxy s2 battery life

Hey people, i am a starter in this forum(posting i mean) i ve tried like 30 roms in an year in my sgs2(i9100) and currently on the ressurction v2. Just an information, since i am a noob i dunno if this has alrdy been posted. I did somethin somewhere i read on the net which boosted my battery life to like twice the previous amount..
Here are the approximate battery hours
without net, camera usage, music and games - 25 hours 17 mins(1%)--> Previously it was barely 13 hours
with al the above and 2g on(working apps like gmail fb whatsapp viber etc) i got like 7 hours with 80% remainin ---> previously 10 hrs an t was 0%
With 3g its close to6 hours n 77 % remaining.. previously t was 6 hrs..
Like i said i duno hw much is the actual bttery life o GS2. HEre s what i did(for those who think i am not a "bloatware" )
1. Take a backup of the image audio and the other essential files u need frm ur SD card
2. Go to recovery and wipe data factry data cache and dalvik...
3. Clear the battery data (or smthn like that)
4. Go to settings and clear the SD card(format sd card)
5. nw all the useless app files (Badly written apps) whch consume **** load of the power thru "android OS" re removed.
7. Jus copy bak the essential files and trn off the fone n let t charge to 100% (3 sad hours :|)
8. I think thats bout t.. I got a proper response.....
Mods if this s a repost or smthn please remove it sorry in advance...
Oh and try not to use the chargin process on and off. Charge t fully once n don charge if its not below the critical 5%... sm improvement in battery life
cheers to the noobs n ty XDA..
Interesting will definitely try this out. My battery life is pretty bad.
7 days and still going..
normally my phone lasts about 2 days with few phone calls, 3G and limited WiFi usage.. last wednesday, I charged it over night and today, the phone still has 25% baterry life. I don't know why it happened, but now it's 7th day of using my SGS2 without charging.
I go like 30hours on battery (got the 2000mah extended) with medium to heavy usage all day long.
3G and sync always on
WiFi probably 5-7 hours a day
Auto-brightness with LUX
A lot of whatsapp, twitter, facebook, instagram, etc

Any proof? Like screenshots..?? My NOKIA 1500 doesnt give more than 4 days.. Ur phone is a BOON!!
I get 1 week!!
when I only turn it on to check the time :meh:
seriously...
wifi on 5 - 7 hours!? Using wifi saves battery i.e. doesn't drain it
Before my ph would run dead flat? - probably 36 - 48 hours depending on whether it's under heavy or moderate usage.
Think I may invest in 2000mAH battery to get 2 days out of ph...
I use my ph for work - so I charge it every night if it's below 50%...
Sounds interesting and logical. There are some apps that create large folders(iFunny=over 1GB last time I cleared)(I also had some random app making app backups without me knowing ).
I'm now flashing Hydra rom so I could try this out right now...
My record is about 3 days and 3-4 hrs but with minimal usage. With my normal usage I typicaly get about 2 days on ICS and a day - day and a half on GB.
My normal usage is some WiFi/H+ browsing or file transfer, a few pictures, music, a few calls and SMS and a coupe of apps, about 10 or so emails per day, lots of time and weather checks and etc. Generally I'm quite happy with the battery life since the move to ICS (stock, non-rooted).
I noticed this too, I backed up my phone and moved my files to micro sd, cleaned the internal storage and backed up apps,files you don't need to pc
you do get performance gains, my media scanner is shorter and its less awake if so,
i noticed as ics isnt 100% backwards compatible so androidos and media scanner was not far from display usage in battery information
OR you can just install Greenify without loosing any apps. Its on PlayStore, though it needs root. Perfect I'd say. Check it out.

I get a screen time of around 6-6.5 (full time on screen) hours. with EDGE on. so id say this is not the worst. your phone has been awake for like 4 hours. And you have active apps such as fb viber n whatsapp. And downloads as well. First usage can be inaccurate just try two to three full cycle charges and then get back im sure it will improve

Awesome battery life - inadvertently achieved

I have a few Note 10.1's (for work). Part of the process to get them ready for use is to disable all the "extra" apps which come on the Note. I was working on one earlier on Thursday and then got swamped with other issues. I picked it up this afternoon (over 48 hours after putting it down) and it is at 94% battery life remaining! Gmail sync and Wi-Fi are on. Google+ and all Samsung installed apps are disabled through the Application Manager. Power Saving mode is disabled.
I am amazed that this tablet could sit powered on for a month and still have 10% remaining charge!
Agreed. I noticed the same thing a couple of days after getting my GT-N8000. Standby time on this bad boy is epic:good:
The actual screen time on this is even more amazing (at least in my opinion). I can easily get 10 hours from full charge and perhaps even 11-12 hours sometimes. This is with constant browsing and even some gaming. With similar thing, infinity lasted mere 5 hours. With galaxy note 10.1, I have finally stopped looking at my battery use every half an hour..... Well I guess I lied.. I still do that only because I am just simply amazed with Galaxy Note's battery life, and still in doubt mode how well it does.
Yeah battery life is sick. I pulled over 10hrs. Of on-screen time the other day. With constant heavy web browsing and gaming. I did have power savings mode as I was testing if any noticeable drop in performance. Which actually there was none. I played Nova3 in power savings mode and it didn't miss a beat. Which shocked me because once CPU mode in power savings is activated, the Max speed is 1ghz on one or all 4 cores. CPU spy confirmed this. Battery life is still great in regular mode also.
The battery life of my N8000 (compared with the P7500) is incredible. The P7500 was down after a usual work day in an area with poor GSM coverage. The Note 10.1 instead is now in the late evening just below 70%.
Battery Life compared to iPad 3
Howdy All Y'All,
I got my GN10.1-16W on 25 Aug from Amazon. I've owned an iPad 3-32GW for a couple of months now. I've found the GN10.1's battery life to favorably compare to the iPad 3: getting 8-10hrs of use on both.
Impressive Samsung!!!

Cancel that - didn't scroll down far enough. The disabled apps show up at the bottom of the apps list in All view
may anyone write wchich apps should be deactivate to achive amazing battery life?
Also very happy with battery life. When t got it I tried running it down before first charge but after four hours of continuous use it still had 30% battery left so I gave up and just charged it.
Its interesting because I read reviews which suggested nexus 7 has better battery life. on the N7 I can pretty much watch the battery drain before my eyes, so I'm guessing Asus either over estimate their battery figures or Samsung underestimate theirs.

I meant to post this the other day but yes, a running list of apps disabled would be helpful . Im getting a very good battery life but not quite 10 hours (well maybe with power saving mode)
Also, approximately what screen percentage is everyones set at and do you use power saving mode to achieve these results?
i get great battery life setting my brightness no higher than 20%. note gets really good battery life. especially in standby.

[Q] Battery Issue When Adding Exchange Push Email

Since you use company email, your's phone sync always turned on and obviously data connection on. Both of these are battery hungry operation.

Help me understand my battery

Nexus 6p running 7.1.1 beta. Rooted, but running stock ROM and kernel. Only modifications are Pixel launcher and Google Assistant. Brightness at 10-15%. Wi-Fi is on while the screen is on only, but Bluetooth and mobile data are always off. Location services are set to battery saving. Screen timeout set to 30 seconds. Adaptive brightness and ambient display is off. I'm only getting 3hrs SOT, but standby time is great. Only watch one hour of YouTube altogether and use social media often. Is this good or is there something wrong with my battery? ?

Nexus 6p running 7.1.1 beta. Rooted, but running stock ROM and kernel. Only modifications are Pixel launcher and Google Assistant. Brightness at 10-15%. Wi-Fi is on while the screen is on only, but Bluetooth and mobile data are always off. Location services are set to battery saving. Screen timeout set to 30 seconds. Adaptive brightness and ambient display is off. I'm only getting 3hrs SOT, but standby time is great. Only watch one hour of YouTube altogether and use social media often. Is this good or is there something wrong with my battery? ?

Install a battery app like GSAM and you can see what is using it, or things that may be causing wake locks.

Try a factory reset. Factory reset mostly fixes such issues of wakelocks.

Tried that and wiped the cache partition. No luck. I'm pretty sure it's poor optimization on Nougat. Hopefully Google will fix it.

Even i was on stock Nougat for a long time...but i didnt face such issues yet. Infact i think Nougat optimizes better than Marshmallow. As battery backup has substantially increased...a bit.

Oh well, maybe the next update will make it better

Well it may also depend on ur battery life..not all phones work the same as they must .
I seriously thought that such a big battery and the optimization that I 've witnessed on many other Huawei devices would mean that I would get better battery life.... How to fix this people.... Help!

Private messages are not for chats, more so if it concerns others too, if it can help others.
You can write thenumbers that bother you, and we then can say if those are bad or not.

I get 4 hrs of SOT
Average use daily is checking e-mails - checking Facebook and Twitter - Youtube and Music streaming - no games.... Sometimes, it drains without even doing that and I barely pass a day without charging it.....
PS:
The Screen on time is inconsistent as it might be just 2 hrs or 3 hrs and it would be consumed completely!
Is there a ROM or an app or anything that can help me get better SOT?
Thanks and apologies for the message, I now know that it was unnecessary.

As I said earlier, and I can't stress it enough, install a better battery monitor such as GSAM. You can see exactly what is using your battery and what is causing wake locks. It is the best first step in trying to fix drain.

12.7% per hour of use (that's what the GSAM says)

Make sure you let it run for a couple full cycles and you have to read it correctly. You can't get useful stats the minute you install it because it needs to run through full cycles while charging and unplugged, as it can only provide information for the time it's been installed. The longer you run it, the more accurate it is. Second, the App Usage stat is a percentage of the percentage of battery used. So if your battery is at 70% when you look at app usage and it says those things used 57% of the battery, that's 57% of the 30% used to that point.
You also need to look at the Held Awake stats because that will tell you what, if any, processes are keeping your phone awake and thus contributing to drain.
I have found that the system in Nougat does tend to use more battery than it did in MM. However, doze implementation is better and it deep sleeps more and does a better job of saving battery. In fact since Nougat, I've stopped using Greenify because it actually seemed to make my battery worse. Since I've been on Nougat I get well over a day on a charge with about 5-5:30 SoT. However, battery also comes down to what ROM and kernel you use and how much you do processor and screen intensive tasks. Music streaming doesn't tend to use much battery, but if you spend a lot of time web surfing, Youtube and games, you'll cook your battery no matter what. If you use the Facebook app, nothing you can do will help as it's a dreadful battery suck.
Here are the numbers provided by the GSam App
Are these numbers good or bad?
The average use gets me through the day but if I use it heavily, it would last 3hrs max.
