Uptime: 2hours 27minutes and x amount of seconds and dead.
did I break the record for stress testing it?
Anyways, anyone got any tips on battery life? I was thinking of getting 3000mah or 3500mah, but the design of it (bulky) just doesn't seem the right option in my mind.
Also anyone here actually have the 3000mah or 3500mah so they can chime in on the design + battery life compared to the original?
just powered the phone back up. and it says battery is at 50%. wtf.
It turned off on its own cause of low battery, and now it says 50%?
E-gad the ghost recharge strikes again.
I had the same thing happen this morning. Woke up to a dead phone, plugged in, boot ed and battery showed around 70%... Go figure

Battery may not be calibrated correctly. I have to say my only major disappointment with the EVO is how the battery life is so tied to the particular rom I'm using. I mean I expect different drain rates on different roms, but having to recalibrate the battery every time I switch roms is just plain dumb.

Juice defender did not do it for me either. I got 1.58 but too many things were turned off to get there. What is the purpose of a smart phone if everything has to be turned off to save battery.

It used to work for me, but now it is doing the same thing. Im at 1.76 now but for the past week it was stuck on 1.00, then slowly went up with each flash.
just a quick update. The reason the battery showed empty one minute and then it showed 50% the next was because of the heat. The phone was very hot when I was playing with it, and then when it cooled down it seemed to have fixed itself or w/e. Happened again today.
im sure its been answered..but how do we calibrate the battery?
Pretty sure you can erase the battery stats through clockwork recovery. Also there is a way through ADB which is pretty easy too
Sorry I don't have any links atm.
Hello everyone, i purchased my Nexus 7 and it arrived in the mail 3 days ago. And as with every other Android device ive ever owned, the batter is absolutely terrible. I get about 2hrs on screen time when browing the web and maybe playing an occasional game. Does anyone have any idea whats going on? Or have any way to help? Thanks so much
That is pretty bad. Try a factory reset. Might be something you installed.
I'd hate to do a factory reset cause I just barely got it set up but..I'll try it anyway tonight

Doing a factory reset before installing anything is becoming the gold standard.
Hope it helps you.
I get between 7-9 hours of active use. Sounds like some process is running amok on yours. I didn't factory reset when I bought it either....though I have rooted it since then, but battery life is about the same pre and post root.
You might want to consider a program to monitor battery use to see what's eating it up. Maybe do that before you factory reset it so you don't install the same thing again.

System panel is a good app to find what's using your CPU and better batterystats can help find what's keeping your phone from going to deep sleep. An easy way to see if this is the case is go into battery setting and select the first option(history details). Compare the Awake bar with the screen on bar. Those two should be nearly identical if not then you have a rogue app.

The one I've seen mentioned several times in here is BetterBatteryStats. I just don't want to drop $3.00 on something I don't need. It might help your issue though.

have you flashed any kernels or roms? sometimes this makes the tablet report the wrong battery stats for a bit.
did you run the battery down until it turns off and then give it a full charge? sometimes you have more juice than what is being reported. ive been stuck at 1-2% for over an hour before. Most likely its a rogue app though, system panel and better batterystats should find out what app it is. if they dont then it could be that you have a defective battery...
Been on mine continuously for 3 hrs 18 mins and at 60%. Excellent if you ask me. Next step up in battery life would be Transformer series with dock.

Quite the opposite for me; unlike every other Android device I've had (Nexus One, GS2) the battery life is excellent. I watched 720p mkv video on the train yesterday for a good 3 hours, and still had ~70% by the time I got home, from a full charge.
The battery life is excellent, as far as I'm concerned.

Don't think you needed to calibrate the battery to begin with. I usually get fine battery life without doing anything special.
Something must be causing the poor battery on your Nexus, Yesterday after my N7 was fully charged, I watched the movie Thor for 1hr and 54 minutes n and my battery only dropped to 83%.
I'm at 16 hours and 52 minutes with 3 hours and 44 minutes of on screen time, the battery is at 51%

My N7 is completely stock and has never been rooted. I also did do a couple charge cycles which didn't seem to help much. And better batterystats has AudioOut_2 at 38% (while I'm playing music) but other than that it doesn't seem to be a rogue app

Unless you listen to music for over 5 hours or streaming the songs it shouldnt use that much battery. If you can't find a wakelock with better battery stats then it might just be a bad unit.
Hi guys
After two weeks of trying to solve this myself I'm completely out of ideas and desperate. My phone is an international d802 running on a strong Australian 4G signal.
No matter what I do I seem to be getting around 3%/hour battery drain when the phone is idle/sleeping.
I've been analysing with betterbatterystats and wakelockdetector and my phone seems to be deep sleeping 99% of the time yet the battery still drains.
It the past couple of weeks I have experimented with Stock LG, Cleanrom, Cyanogenmod and Omni as well as a custom kernel and the drain happens on all of them.
The test I performed last night involved
*Completely wiping my phone restoring the factory image
*Running setup and only installing betterbatterystats (wakelockdetector was installed this morning after the test)
*Disabled WIFI, BT, GPS, Location Services, NFC and Sync.
*Leaving the phone on my table unplugged but not in use.
*I woke up half way through the night the check the result and when I noticed it was still draining I disable data for the 2nd half of the night.
I've attached some screenshots of what betterbatterystats and wakelockdetector had to say ignore the flight mode I only put it in this mode for the last couple of minutes.

More screenshots. I only installed wakelockdetector this morning after the test to check what it had to say AFAIK it should still have accurate results despite this.

Ur crazy and without signal.

For this test it should have been nothing as it was a complete fresh install with no user apps other than BBS. I manually disable all of google syncing in the settings menu. I've performed similar tests in the past couple of weeks with my normal daily driver setup i.e CM with a few apps running and sync/bt/nfc/wifi/data enabled and it produces very similar results.
This test was just an absolute barebones "control" test to rule out anything I could have installed so I was shocked to still see the drain.

I'm not quite sure what you are trying to say? If you are referring to the 3hrs of no signal in BBS that would be when I disable data for the 2nd half of the test.
Ok after another night of testing I'm at a loss.
This time I tested in flight mode the whole time which should rule out any sort of radio issues.
To my shock I lost 25% overnight at 3.2%/h screenshots attached.

No its not. I usually drop about 2% in 8hrs with LTE on, being when I am sleeping and not touching the phone of course.
Oh dear this isn't great news though on one hand I'm almost strangely relieved as I've been going crazy testing every possible solution for the past couple of weeks.
Now the bad news. My phone is a grey import (so I could get the international model before the local model was released) so warranty/service could be a massive pain if at all possible.
I'm now looking into purchasing a replacement battery. The only one's I can find are on ebay for around $60 delivered and then I'd need to pry the phone open to replace it.
Is there any way I can 100% confirm it is a faulty battery before spending more money? I do recall certain tools during my testing describing the battery health as good but I don't know how reliable they are.
Voltage leak indeed. Could well be a bad phone and boot just battery.I may lose .1-.2% overnight airplane mode. Sry bud.

I'd have to agree with the majority here and blame it on a bad battery.
See if your location options are on, if they are, turn them off and try again.

Yes someone actually advised that to me on the whirlpool forums earlier so I did that very thing last night.
Just turned it on and it was on 98%. Not sure what to make of the result??
Bad phone or battery is the result.
Hey guys,
I've joined the club and bought an Axon 7 A2017G.
In my first 2 days of usage, I noticed I needed to charge the phone at least twice per day.
After reading quite a few threads about this issue, I installed GSam battery monitor. It lists my SOT as 1hr 13 minutes, and battery life at 10 hours.
At turning just about everything off, installing Greenify and applying aggressive doze, I was no longer getting a wakelock.
I have however found that GSam shows that my screen is discharging over twice as much battery power, as compared to having the screen on.
I was wondering if this was normal, and if not, any suggestions in increasing battery life?
Not normal try a reset.
Something keeping the phone awake, haven't used gsam in ages.. betterbatterystats is far superior in helping track down what's keeping it awake but requires root.
You can use this app to access original battery stat. Works very well.

I'll try that next. I've just completed a factory reset, so hopefully that helps out.
I found it quite strange that Screen Off used more power (52%) than Screen on (20%).
GSam didn't report any wakelock, and the phone was in doze quite often.
Seems that the factory reset has done the trick.
Now trickle re-installing apps.
Fingers crossed that battery usage stays relatively normal.

How's the battery performing now?
Mine seems mediocre. After charging overnight I usually need to charge in the evening. I get about 10hrs per charge with 2-2.5hrs SoT. Are you getting better results than this after the FR?
Thanks!

As GSam hasn't gotten all required data yet, I will go off what Android reports.
I have used 30% of my battery in 9 hours, with approximately the screen on for 3 hours. Bear in mind that I've had wifi on for approximately 5 hours with a mixture of screen on and off.
Just having a stab in the dark here, but, two apps that I haven't redownloaded are Swiftkey and Nova Launcher. Instead I installed GBoard and Google Launcher. Don't know if that had mde any difference.
So yes, far better results after the FR

I also did the force update to B09 before the FR. According to ZTE it offers improved battery performance, but I didn't notice any improvement from B08, whilst I used it.

I was a little confused what you meant by B09 but I see you've got the A2017G. I'm on the A2017U so I think my equivalent update is the B29 which is what I'm on. I've got tons of apps to backup so I'm going to try resetting tonight. Think I might unlock the bootloader and consider rooting while I'm at it

I've been using cm13 and sometimes Android system drains too much, so I will go to TWRP and wipe dalvik cache and it greatly improves battery life. Takes 20 minutes, but is great for getting 5.5 hrs sot.
Hi all, I'm just wandering if is there any way to check battery health ? an app or something.
Tried several apps on Playstore and all say that my battery health is good, but I'm having a battery drain and shut down from 25%.
thx in advance.
Try Accubattery, it showed the issue with mine when it was doing similar before Google replaced it.

Interesting. I made the mistake of charging overnight at first. I only realised a while later that it only took 1 hour 45 or so to fully charge, so now I charge when I wake in the morning. Overcharging is supposed to be the main cause of battery depreciation.
When I first installed Accubattery I was at 91%, that was the end of June, don't think I'm doing too bad.

Like every Nexus phone I've owned ... since the Galaxy, I have left the phone on the charger 24/7. All day, all night. I take it off when i leave the house/office and sometimes it stays on the (stock) charger for days. The N6P has a high number of defective batteries, but that shouldn't change your daily charging habits. In other words don't change charging habits if the one device you have has a defective or sub-par battery. Put a new battery in and carry on. We have 3 N6P's in the family and they are all still above 90% according to Accubattery... Guess we are lucky.
