I've had my nexus s (9020a) since late November (bought it used, in execellent condition.) While battery life was never awesome, it was at least bearable - until last week. I'm now unable to get more than 6 hours on a battery with super-minimal usage. For instance, today, as of right now, I have 5h 58m 57s (at 7% battery left) - the top "user" being the display (32%) with a "time on" of 17m 30s. Even when I power the phone completely off (not the screen, literally powering off) - say for a half hour or so - when I power it back on I lose substantial amount of battery.
Some other details:
Currently running stock 2.3.6 rom (since yesterday), but rooted.
Previously was running stock ICS (flashed the tmobile 2.3.6 ota, then ics, then the att radio) - was fine for the last 2 months
Tried brand new battery (not a samsung, but Anker) - no difference
Tried several different charges, and charging via computer
Have wiped battery stats several times (and done complete resets/formats of everything in between swapping roms)
Phone used to always top out at 95% when charging - but now will go up to 100%
This behavior started up when I was on vacation - a few hours after landing in SLC, UT. I do recall a sudden crash / reboot of the phone before the problems started - but I have gotten random reboots in the past. Was running ICS at the time. I thought maybe a poor signal was to blame, but again, the battery would drain even when the phone was powered off (or in airplane mode.)
I'm not sure what else I can/should do - short of calling Samsung. I'd think if it were a hardware issue, it would fail to charge completely. Does anyone have any other ideas or suggestions?
Thanks in advance!
Sounds like something external is draining the battery. I've seen many cases with a magnet on them drain the battery very quickly, or possibly excessive heat. If not i would say it's some kind of hardware problem.
Does not sound like android chewing it up.

I don't have a case on it - just a screen protector. The battery does tend to run in the mid 90s fahrenheit (according to battery status apps.. though I think I have seen it as high as the low 100s (maybe 102?) - but I figured that was normal.
Another weird behavior I should mention: sometimes when I power off and on while charging, it will cause the battery percentage to jump considerably. Right now, two consecutive on-off-on cycles (within the span of 3 minutes) caused the battery percentage to jump from 36% to 44% to 57%.
Heats normal. Not sure what it could be to be honest. Maybe grab a can of compressed air and spray around the back, maybe dust causing a short or something.

Thanks, will try that
Sent it back to Samsung for "repair". As I suspected, all they incompetently did was re-flash 2.3.4 and say "passed all functional testing". Phone is still hosed and completely useless as-is.
(Fully charged, overnight - less than 8 hours - went down to 17%, with no apps running, no google accounts, no sync, no background anything, no screen time, no wifi, in airplane mode)
Samsung really is hopeless. Going to try again with them? Whatever you decide, best of luck. Hope it works out for you.
what is the mv reading when the phone is fully charged? Fully charged should be around 4200mv

Trying again, but not optimistic. I talked to about 4 total "customer support" people today.. at least got them to "upgrade" me to 2-day shipping for sending back and forth instead of the normal ups ground.
It is so foreign to me - coming from Apple where, under warranty, they'll pretty much swap problematic devices out for new ones _in store_ on a dime. I pretty much begged Samsung to just send me a refurb unit to replace it with but they said thats "not their policy."

I don't have it with me (send it back for round number two) but I am fairly certain that is around what it was reading.
The thing would even burn through battery when powered off, if the battery was still left in. Taking the battery out = no drop. It has to be something hardware.
I am curious about the battery in the one x, and especially the habits of consumption.
I have been around the block with android development. I had a captivate before this, and managed to get great battery life out of that! That was much more simple however. Flash a rom, cycle the power, cycle, cycle, cycle. Then you're good to go.
I feel like the way that the one x deals with the battery is different, more advanced. Some bootloader level software that is untouched, like the hardware keys and whatnot.
My battery has been hit and miss to say the LEAST. I use BBS to take care of wakelocks, keep data and gps usage to a minimum (my regular use), and I charge my battery when the phone is dead up to 100%.
The back of my one x gets very very hot sometimes. This varies rom to rom. Started with stock sense ICS, took the OTA jelly update, now I am rooted, s-off, and on cyanogenmod 10.2 nightlies (which run insanely well btw). The issue is the same. It reacts the same, and is just as unpredictable. I have read about this, and know its a hardware issue, but I am still curious about it, as I have heard SO many different things. I am usually able to quickly curb the issue by turning on airplane mode, or turning my phone off (for a while, as rebooting doesnt seem to help).
In passing, I also read something about "HTC Charge Mode". I have read forum posts where people say things like "hold both volume keys and the power button for two minutes, this with re-calibrate the battery circuit." There are so many combinations of keys and timings that people talk about that I can't help but believe that it is all garbage.
The heating up is typically caused by camera usage, data (radio, I assume) usage, games (temple run 2, gyro), and sometimes even spotify (offline playlists). Wifi seems ok, not too much of a contributor. When I was on stock sense jellybean, I was able to fix a lot of the heating up by turning off "google location services".
The weirdest part is that if I feel the phone warming up, I can go into airplane mode like I said, and its fine. If I keep perpetuating it, however, it gets very, very hot. Hot enough, im sure, to melt soldered connections. I turn on airplane mode, and it doesnt get much better. This is when I have to turn it off. Sometimes it hurts my leg in my pocket if I absentmindedly leave data on.
So I want to know -
1) what is the deal with the battery on the one x
2) can I cycle the power like I could on my captivate?
3) if you know anything I don't about the heating up issue, please share
Thank you so much for reading! I look forward to the possible feedback!
TL;DR - please read the post! I'd really appreciate it!
One thing I do know is that after doing your initial few charge cycles when flashing a ROM, it's better to not actually let the battery level get too low before charging. I read an article by a battery scientist, he stated that continual full discharging of the battery will decrease the long term battery life. So, it's best to do top-up charges from ~40% to full charge. Obviously you can disregard this when doing your initial charge cycles.
Some of these phones heat up more than others. Having the phone in your pocket or any enclosed space for an extended period of time will encourage it to heat up. I can't remember the technical term, but it's a combination of there not being enough air flow around the device to facilitate its cooling down, and nowhere for the heat to go. So it just gets worse.
So knowing that, there are some steps you can take to mitigate the heat, even if only in a minor way.

I took advantage of the BOGO offer from Verizon and got two LG G5 at Costco. I've been using my phone lightly, but I can't help but complain about the major issues that gets everyone else talking: Battery life.
I see other people have screenshots of achieving 6-7 hours of SOT, but I'm seeing nowhere near that. The most SOT I can see is having 3 hours before hitting to a depleted battery. Occasionally as well, the phone feels pretty hot to touch when it idles or have some fair amount of usage. Even right now I have it inside a thick, bulky protective case, and i can feel the heat from the back. Is it the SD820 or is there something off?
Just to make a comparison, I have been using the Sony Xperia Z3v for a year and a half with Verizon since its release and it's a great all around phone. I usually achieve 5 hours of screen on time or even more depending on how heavy I've used it. Waterproof, dual front facing speakers, 20.7 MP camera (although very outmatched by the G5's), and the power saver absolutely works. What I mean by that is that when the power saver is on in the G5, nothing seems to load at all.
So the overall question is, how is this phone for everyone? I absolutely love the camera, but the battery drainage and overheating is an issue for me. I've had thoughts about exchanging for the S7 Edge since it's pretty much a direct upgrade of my Xperia, but I'd like to see what the G5 can really offer. Oh and, how long is it until I get the extra G5 accessories from doing that bundle deal? Thanks.
You know I've noticed peoples complaints about that but to be honest I think its just certain phones that had these issues. I don't know how but mine hasn't been hot since I first set it up. My battery life lasts me a full 8 to 10 hours depending on if I do too much gaming or YouTube. Those are my biggest battery abusers. But I made sure to deactivate the bloatware Verizon wanted to install. I've had a good experience with mine. The only time I've been mind boggled was when out of the blue chrome would cause the phone to freeze up till I reset chrome. Other than that my device has been running so smooth.

I've been one of the people complaining about battery life. In the first week or so that I had my phone, battery life was miserable. I need to be completely honest here though. After getting into my second week of using this phone, my battery life has greatly improved. In my honest opinion, I think it needs about a good week to 'settle' or 'break in'. I've done nothing different done I set my phone up and I have deleted any apps or anything. I don't know if this is the case for anyone else or not.
I like the phone a lot. It is fast and everything works well.
The only things that I want improved are
1) Screen brightness adjustment. Too dark in dimly lit areas and too bright in normal room lighting.
2) Battery Life. This is a strange one. Some days I have really good life, but sometimes the standby use it high. Google Play Services sometimes eats a lot of battery. I have to reboot to get it to stop. There are also people saying that being on wifi causes more drain. I thought this was not true for me, but I am rethinking. It may be higher when I am at home and on wifi.

So far, I've yet to achieve substantial screen on time. It's really strange, I was having my phone used from 330 to 830 tonight, and it went from 100% to 45% with only 50 minutes of screen on time. WiFi and mobile data off, and I wasn't taking a lot of pictures.
One thing strikes me is the Held Awake/Doze clarified by GSam. That's eating the most battery, what exactly is it?

Honestly, I'm not positive. Make sure in your display settings, though, that you have 'screen always on' turned off.

I haven't been able to figure out why sometimes GSAM shows very little held awake with the phone deep sleep for a majority of the time and sometimes the held awake is almost the entire time since the phone has been unplugged. It seems that if the phone gets into the held awake state that you can get out of it by rebooting, at least it seems like that to me. I have not had enough time to come to firm conclusions on this. I am pretty sure that the held awake has something to do with Google Services or Play Services. It would be great if we can get root and limit the wakelocks from these. Just have to wait on that.
Pretty solid compared to the G4. No heating issues, battery lasts longer as well. I'm at 25%, 11h 7 min on battery 2hr 53min screen on time.
I average 14.5 hours total, 3.5 screen on time. I have noticed turning wifi off when I'm not using it saves a pretty decent amount of battery, which is odd.
I'm not upset with the battery life or anything, it's better than my S4 and G4 were, but if the S7 really lasts 7 hrs with screen on.... i don't know. I have another week to decide on restocking. I do love how quick it is, it's beautiful, feels great in the hand, and the option of removable battery.
I like this phone, and while it is better than the G4 in every way (very buggy, lag, missed taps, etc), I now get paranoid about any tiny bug on this thing and wonder if a Galaxy would be more reliable.
My first full charge I got 45 hours of battery life with 4 hours of screen on time. However that was before I had all my apps reinstalled and that 48 hours with 4 hours SOT included reinstalling all of my apps. Screen brightness on auto the entire time.
Since then I've only been getting 4 hours of SOT with 24 hours battery life. That's only 4 - 6 hours more of total time on an no more SOT than what my 2 year old LG G3 was getting.
LG skimping on the battery was a mistake.
I have received my P6a yesterday..
And I can feel device getting warm with normal use like WhatsApp, Phone call & Instagram...
Can feel device getting warm even when I'm using Wi-Fi..
It starts heating(because it's more than just warm) when charging...
Any fix or suggestion is welcomed..

When my Pixel 4 XL overheated, it was usually because I was charging and playing games on it at the same time. If it gets hot, then I would reboot it or leave it powered off for a minute. Could that be the case here?
Also, this is a new phone and you just installed a bunch of apps. My guess is that Android is likely evaluating and learning your habits so that it can optimize your battery and other stuff -- so there's alot of internal processing going on causing it to warm up.
Also, if you live in a city where the weather is warm or hot, then that'll make your phone warm or hot as well. So far, my 6a hasn't stayed warm very long except when I was transferring over/installing all my apps ... and it hasn't gotten hot yet.
The phone does get very warm, but it is also the middle of summer and we just set everything up. Tensor is also known for running on the toasty side. Unless your phone is warning you about excessive heat, it is within normal parameters.
it runs definitely warmer than a pixel 4 doing the same stuff.
I have sensor genius installed so it's logging temp 24/7. please do the same and let's share the graphs.
Mine is running substantially cooler using LTE rather than 5g, hopefully this is fixed through software updates.
I also put mine in LTE mode and it's much cooler. 5G is a bit overkill for mobile stuff at least for me, I just turn it on when using hotspot.
Ok, finally experienced the heating issue just doing normal browsing on LTE. Battery temp got up to around 43c on a cool day with no sunlight.
After some searching I found that turning off adaptive connectivity helps. After turning that off, temps are much better. I was in an area with poor signal so that likely was a part of it, but something else to try.

Another option to try is Disable Adaptive Battery, Disable 5G(If not necessary)..
I wouldn't worry too much. I absolutely assassinated my Pixel 3a XL. It was always hot. For couple of years. Huge amounts of onscreen time. Leaving it under blankets while charging on accident etc etc... Thing was fine. Also, a battery is only $12 and these pixels the easiest phones to open if you do somehow end up with severely reduced battery life couple years down the road
It's more the insane battery drain that goes along with the heat then the heat itself.
May be a CPU usage app that tracks what's taking up so much processor power.
My issue went away once I turned off adaptive connectivity.

Same. As in my country there is no 5G yet, I've changed to LTE preferred and phone is not hot anymore and battery doesn't drain.
It'd maybe gimp the overall performance some but u could try under-clocking your CPUs with FKM or EXKM while u track down the issue. (that is, if your bootloader is unlocked...in which case u could use BBS to track battery usage)
Many complain that the Pixel 6a gets hot or overheats. I have also seen videos were people claim it's only in the beginning while the phone "learns" your usage habits and how to optimize itself accordingly. But later on it doesn't need to run all of its processes like in the beginning once it figured you out, so to speak. (The exception being when you record a 1080 video at 60 frames, which even later on can get problematic.)
Can Pixel 6a users chime in here and recount their experiences? Does the overheating last past the first few weeks after purchasing it?
Bonus question: are the signal issues some complain of widespread, or not?
-----
I really want to get this phone, but I hesitate due to these two issues.
I didn't have overheating issues since I bought the phone 3 months ago.

I have my 6a 2 weeks and I don't have any issues with overheating or bad signal.
Thanks.
Anyone else?
Overheating in the sense that it shuts down with a warning? No, never. But the phone does get annoyingly hot, especially when charging even if I'm not using it at all. That's the phone plus the weather in my country isn't helping. Phone regularly touches 40° according to battery guru, when charging can go up to 43°.
On WiFi things are very normal. Mobile data however is a very different animal. It you have poor signal especially expect this to get pretty hot. Like stated above though, not shut down hot just hotter than what I consider normal. 35-40c battery temps on stock with those conditions isn't unusual.
Initial setup for sure gets toasty as well.
For whatever reason (latest updates maybe?), I've noticed recently that not only does my 6a not overheat, but the battery consumption has dropped significantly. At my admittedly low level of active usage I can easily go two days and still be over 50%. I might try for three full days soon.
I dont have any problems with overhiting , i have phone about 30 days. Playing games recording at 4k no heat problems at all.
Damn bruh...another 'overheating' thread?
Yes. The 6a may get fairly warm in some specific use cases, but it doesn't actually overheat as in start throwin' out warning messages and start throttling or worse, crash/reboot that I've ever witnessed. Actually mine seems to run slightly 'less warm' since A13's beta 2 & 3...just before I flashed a custom kernel. A few things to consider besides differing usage scenarios. If you're using a case, it may not only hinder cooling a little but probably 'feels' less warm due to the insulating properties as well. I try to go with a minimalistic case...it may not provide a lotta cushion if dropped but I'm hoping the improved grip offsets that point. And ofc the thinner the skin to less it retains heat. I went with a grippy Spigen Liquid Air or something like that.
Above all, I keep in mind that the 6a has the same processor as the [email protected] P6 PRO and that also helps me to forgive n forget that it can get toasty at times...plus thst resulting Tensor 'grin-factor' tho...
...just my 2 centz ofc
If you're using mobile data or using the phone as a hotspot thing gets very warm.
Normally, I've only experienced the phone getting very warm when I'm playing a game and charging the phone at the same time. However, on a recent trip to a foreign country, my phone (and its camera) stopped working because it was hot outdoors (around 80°F) and I was outside for 30min or longer. My friends' iphones didn't overheat though.
I haven't experienced any signal problems.
Mine never overheats. Its just warm enough to be a hand warmer, but not enough to damage anything

...and it displayed an overheat popup warning? 'cuz it was 80F outside? I've been out with my 6a dozens of times in 80F+ weather and NEVER had my phone throw an overheat warning much less shutdown or lock up. You might have something wrong with ur phone if a warm day kills ur phone...js

No overheat warning. Phone felt very warm, froze up and apps would barely respond or it would keep on rebooting. Tried a few times to power off, wait a minute, and then power on to get that last photo, but didn't work. After I got out of the heat for a short time, phone went back to normal. Felt hotter like 95 degrees, but weather report said 80s.
Nothing wrong with my phone per se. My guess is that my phone was in direct sunlight for 30 min. I myself was dying from the heat. And before that, I was already taking pictures on and off for an hour (in the heat but not direct sunlight). I've used the phone before in hot weather without issue, but this time around, it was continued use and in direct sunlight.
My 6a definitely overheats and shuts down sometimes without warning. This has happened numerous times even when the phone is having light use (chrome or connected to android auto). I would say there are 2 factors. When the outside temperature is hot (35c or hotter - which currently in Australia is a daily occurance) and when the signal is not strong (also a very common occurrance here) - when this happens the phone can overheat and shutdown within minutes even with little use.
From my exp. signal strength seems to be the biggest issue. The pixel seems to literally burn through the power when signal is weak and get hot.
Generally I have had a 50% chance of getting a 'Your phone is hot' warning - other times it just turns off.

You should RMA the phone. Sounds like a faulty device to me.
Also, just hot ambient temp does nothing to a phone. If it gets direct sunlight, thats unsafe for the device because of how hot it can get (if you measure temp in your car, it gets up to 60-70C+ easily.) If I use my car in hot sun, I aim an AC vent to its back and then the phone is super chill all through the ride.

Yes, I think I will RMA it. - I don't agree re ambient temp. My phone certainly seems to shut down more often when the ambient is hotter. Also, re the car. I had the phone in the glove box which is separately cooled to 21c and even then it would overheat, - I suspect related to poor signal. But yes - will RMA it.
Try safe mode first. You may have an app which is misbehaving. I've never had my 6a overheat, it will sometimes get a bit warm when charging, but that's it.
