inaccurate estimates on charging completion... - Google Pixel 2 XL Guides, News, & Discussion

so It was 12:17pm. i had been charging the phone for maybe 15-20 minutes already. i looked at the screen and it said "charging rapidly (30 minutes until full)...
i thought to myself, 'cool, i will check it in about 12:45pm to see first hand, regarding the reports of slow charging when upwards of 95%.
well, i got distracted at work, and next thing i know it was 1:10, i glance over at the screen and give it a tap and see... "charging rapidly (33 minutes until full)"..
anyone else notice incorrect estimates on charging time on the lock screen? think this is something that will work itself out after usage? maybe it was just a fluke.. havent really had the phone long enough to notice/test things like this out yet..

I personally don't like the new oreo battery stats in settings. There was a video of all the major phones charge rate review like where they time it and it did charge the longest. But what you have is kind of weird mine is probably similar to that

Quick to die. Slow to Charge?

Have you guys noticed any issue with the charging speed of this phone?
Last night when I went to sleep, 8PM (i know early), the battery was at 9 or 10 percent. I plugged it into the charger and all that. So this morning I go to remove the charger to check e-mail and what have you. 94%.... Come on, its 4:30 AM so that is eight and a half hours and not 100%?
Is this in the experience of anyone else? (Also do not let stock battery meter fool you, it doesn't show accurate measurement of the battery.) If not, what are you guys doing? Or is there anything I can do?
Honestly, 8 hours to charge your phone does not seem right. Something is wrong with your battery. The vibrant does take a long time to fully charge, but never 8+ hours. It usually takes mine a good 3-4 hours when my battery is dead.
I highly recommend download the application juice defender. Research and learn how to use it. It will save you tons of battery.
I'm currently on my 38th hour since the last time I unplugged my phone and I still have 8% battery. Btw, I've been using my phone for phone calls, texting, and playing games.
First of all thanks for the JuiceDefender tip, that looks very promising.
But do you turn your phone off at night to charge? Because I just turned my phone off like 20-25 minutes ago and it popped it all the way to 100% just as I was typing this response.
Any other suggestions, tips, or concerns from anyone, please share.

No, I leave my phone on. Usually with Wifi too.
Also, I have a simple wallpaper that is mainly black (it has some blue designs, but the wallpaper is mostly black). Having a black wallpaper saves battery as well because the color black consumes the least of amount of energy from our screens.
Well my homescreen is pretty black. Black mesh background, black icons (bettercut). Black bar mod. Just got done configuring juicedefender, even bought the pro version. Figure if it doesn't work out I can simply return within 24h. And, I will know within 24 if it is helping the draining.
Leaving Wifi/Bluetooth/etc on will suck your battery down. Turn it on only when you need it. This is true of all smart phones.
My Vibrant will charge to full in a couple of hours from dead. I get 10+ hours on a charge even with heavy use but I almost never use Wifi or BT so YMMV. I definitely get better battery life from the Vibrant than the old G1.
Curious if you could pay attention some time when your awake... my phone rarely charges past 98%. Wondering if your phone is charging up to 94% quickly, and then hovering or if it's actually taking 8 hours to get to that point?
Maybe you should get a replacement.
I can plug my phone in around 10pm and at 6am my battery sometimes says 98-99%, but normally is good to go shortly afterwards. I do turn my phone off at night and those that need me do have my home number too unless I'm traveling.
As well I normal usage is 6am-10pm or so and I have typically 40-60% left on the battery depending on the usage. Yes I do check the About Phone and not relying on the wacked out battery meter.
I don't leave wifi, gps or 3g on all the time simply because I don't need them. Id rather squeeze the battery than have something on that isn't being used anyways. Having that quick settings drop down in the Notification bar rocks.
I have the same issue. It always takes about 4.5 -6 hours to 'fully' charge my Vibrant from <10% regardless of whether the phone is on or off. Then after unplugging the charger, the battery info states that the battery is charged to 96%. My belief is that there are firmware issues with at least some TMO Vibrant phones. I'm also dubious of the USB charger. I've ordered a regular charger and I'll see if my suspicion surrounding the USB charging system is founded. Maybe...

Mine takes about 3 hours to charge but I normally get about 13 hours a day on it with normal to serious use. I haven't had a problem with battery life since I purchased it but I have been trying new battery saving techniques to see how long I could make it last.
Currently using a mostly black background. Wifi only when I'm in the house. Brightness all the way up. Synching two email accounts and Facebook all day. Definitely getting the most out of the battery that I could expect.

Well mine takes a while but not that long. I'm going to try out the juiceDefender that was mentioned but the other thing I would recommend is the accurate battery mods that can be found in the Themes and apps section. You can flash with clock work and it's a great way to know what your battery is actually at so you can see how much you're using for various things.
Make sure your charger or USB port has high current output. There are some out there with only a few hundred milliamps. The phone will take nearly one amp and should charge in a few hours.
Excellent point. For me, I'm using the supplied Samsung USB to 110v adapter and I'm getting 4.5-6 hour charge times.

Also the USB cable is important too. 1 amp over a long, skinny 5 volt cable can drop the voltage. If the charging chip sees a lower voltage, it will think the USB port is at capacity.
I love this phone but I must be honest.. this phone is worst as the Motorola cliq battery wise. it's terrible. I had 100 percent battery life at 8am and at 10:50am I had 23 percent battery left............ no matter what I was doing.. even if I had the screen on full blast *i had it on the lowest* it still shouldn't be almost dead in 3 hours .... smh!

One poorly written application running in the background could be causing the CPU to wake up constantly. Yet I can talk for hours and the battery will still be nearly full.
I know for sure one of the latest versions of Facebook ate batteries like crazy. I ended up installing an older version and my battery life returned.
Update on the issue. I was using juice defender but it wasn't doing anything for me as far as I could tell. I have since turned off vibrate on touch, and noises coming on during clicking. I am using a usb hub with two vibrants on it. I'll plug it into the wall tonight and see how that goes.
I have been turning off my wifi when not using it. A little better I suppose. While typing this I went from 49 to 46 percent and I am a fast typer. No wifi bluetooth gps.

Yes the battery drains pretty fast, and it does take about 3 hours to charge... my main problem is... at night when I plug in to charge, couple hours later I get woken up by a beep and popup window telling me charging is done and to unplug...
anyone know how to turn that off?

[Q] Does battery get better after a day? If not, what can I do?

So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,
Rocky
Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S
I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.
But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky
I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.
The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.
Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?
Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.

[Q] Strange and inconsistent battery drain

I wouldn't exactly call this an issue because it doesn't really affect how I use my phone - it's merely something odd that has me curious if anyone else has it:
If I charge my phone all night, and plug it out at 100%, then no matter what I do it'll stick to 100% for a long, LONG while before it hits 99% - we're talking..25 mins of sat nav, and spotify, and full screen brightness on the go. But then, it falls down into a more regular pace of discharging.
If however I unplug it 5-10 mins after it hits 100%, it starts discharging normally.
I think I can get a batter life of full browsing of 6 hours, probably. Maybe a bit more (never tried it, never needed to).
I am just curious why this happens with my LG. Do you think it's a fault or is it fairly common?
Thanks
P.S. - testing it again now - 15 mins in youtube watching a video, still at 100%. very strange
you seem to have found some interesting sweetspots of charging and battery depletions.
My instinct tells me the discharging and the 100% mark is influenced by code in some way other then the battery being truly at 100%. There is software like android tuner or battery widget that monitors stuff.
however a great dev already wrote something about tinkering on lg's side in reporting the battery. Which means the percentage is. indicative but completely reliable. To gain more indepth into the actual battery usage other apps are needed. If have battery ocd that is.
I would report this to lg, just to be sure nothing else is happening

what is more interesting is that this happens to me both on official LG, and on ROM (cloudyfix).
Continuing with my tests, I have been running youtube on repeat since unplugging and monitoring. I am now at 50%, with...close to 5 hours of usage?
then its playing from buffer and not continiously downloading and streaming right?

So I'll leave with that little flaw I think, I'll just learn not to mind it and be sure to always charge overnight to get the best next day. Thanks for the help
I usually charge my phone and reboot it right after it hits 100%. I don't disconnect the charger until the phone restarts completely.
Doing that I get outstanding battery life

[Q] Galaxy S4 Extreme battery drainage!

Well something is definitely up with my phone and this is nothing like any of those "poor battery life" posts. I'll just get on with it. So recently (the past month or so) my phone hasn't been charging normally, i noticed that the little lightning bolt to indicate charging at the top of the phone would disappear and show the battery percentage every 3 or so seconds. It did this and thought it was the way I held the phone, maybe I had a slightly bad charging port that disconnects with the slightest movement. However today I set the phone flat and watched the same phenomenon happen without any movement, every 3-4 seconds it would say no charging like clockwork, but there was no charger disconnected notification... On top of that my battery life is the worst I've ever had to witness in my short life (ill post a screenshot below). With certain chargers my phone will only charge when completely off, and last night i left it to charge while idle and it only charged to 50% after almost 12 hours continuous charging! Any ideas? I hope its the battery and not any other software or hardware problems. Also the battery shows no sign of swelling tho when idle the temperature sits at around 37 degrees Celsius. Brace yourself for these screenshots...

did you read the post properly? -_-
It's possible either your charger, your battery or your hardware itself is damaged.
sorry to be the bearer of bad news.
Also be careful of in-proper charging on phones.
Lithium burns / explosions are not funny.
Okay, so. I would first try to go back to complete stock and try testing again. If it still happens, try changing the charger/cable since you probably have another one laying around anyway. Then I would change the battery, and lastly the device. Good luck.

Phone shut off at 32% and only charged 7% in 1h30m with fast charge

I work 8 hour shifts and my 6P on Pure Nexus lasts through the shift with ~30% when I get home.
I was listening to music through Bluetooth and when I turned off my headset around 5 hours into my shift, my phone shut off and wouldn't turn on. I was in and out of the freezer, so I thought it was the cold. I got home, turned it on and plugged it in and saw it had 32% left.
An 1h30m of charging and it only charged 7% which is really unusual and is the first time.
I have AccuBattery Pro and it is saying it's going to take 10 more hours to fully charge using fast charge. Android lockscreen says "Charging rapidly. 12 hours until full."
Also in AccuBattery, although my design capacity for the battery is 3450 mah, it normally says estimated capacity is 2200, but is now saying I have over 5000 mah in capacity.
When unplugged, it has a screen on discharge rate of 50-70%/h when the average is 23%/h.
Is the battery dying? I thought it would gradually decrease in capacity and not suddenly change overnight.
When my battery bug hit..it just hit. No warning signs or anything. I was crapping out anywhere from 60%-10% and everywhere in between. I bit the bullet and RMAed for a new battery (they gave me a new screen too for whatever reason) Before i sent it in my Accubattery stats were saying i was at 75% capacity and now ive been at 100% capacity since i got it back and i can happily go from 100%-0% like its supposed to.
Although your situation does sound unique its almost certain you'll need a battery replacement.. or try a new ROM and see if it keeps happening.

Unfortunately, I got my phone from Rogers around November 2015. I don't even know what they can do about it. It's been averaging about 14%/h charging which is about 1/3 the speed. I've been using the same ROM for several weeks with no issues and haven't installed anything new lately other than app updates. I can try upgrading Pure Nexus, but it seems like they have a power menu bug at the moment.
Do you think your charger could be broken?

My wife has a 6P also. I was trying her charger and it's the same thing. I've rebooted twice. It's still draining at least about twice the normal average when disconnected.
So it's roughly draining at about twice the normal speed without doing anything and charging at a third the normal speed.
I seriously can't afford to replace it. I regret choosing a phone without replaceable batteries and will not do that again, which means no Pixel phones. At least I still have my Galaxy Note 3 which still works.
if i were you id backup the entire phone (or whatever is importannt to you) to my computer and download the J factory image and do a fresh clean flash and pray that it clears out whatever is going on. Sucks to start fresh, but worth a shot

I use FolderSync to backup my phone nightly to my NAS server.
The slow charging speed may be due to high cpu temperature. It was hovering around 40° for whatever reason. I set it down on a cold granite window sill and the temperature dropped to 35° and was charging at twice the speed, but still slower (1000mah vs 1550mah from before). I've been holding it for a while and the temperature is again going back up with charge speed slowing. Again, I've never had this happen before.
Thanks again, I'll probably restore the phone and bring it to Rogers later this week to see what they say.
