Hello,
I need help about battery replacement,
Let's tell a short story:
I bought my Zenfone 2 from a technology supermarket (it's a national one, so it's reliable), a second-hand Z008. When I first bought it, it was running stock LP and I rooted it 2 days after. At that time my battery was still very good (>4 hrs SoT). 1 month later, I go on vacation, use it all day and get about 3hrs SoT. I accidentally bricked it then. I received it 1/2 months later from Asus service centre, battery life seems got worse (4hrs SoT). 1 months later, I went on vacation again, the battery problem started here. I used it all day and get 2hrs of SoT, but it drains very fast at 20%, and overheated (.69 beta MM), it went 20%-0% in a few mins. I wiped /data and the battery seems little better. 1 months later (recently), it started to get VERY BAD. after a full charge, 9mins SoT = 5% with Facebook on wifi. Only 2h30 of SoT with Facebook and Messenger. I've used all rom to check whether it was a software bug or my battery is facing a big problem. Stock LP, stock MM, CM12, CM13, AOSP has the same battery consumption : 2h30 of SoT. Now it charge very slow, it can't even reach 100% (very few times it can reach that).
Should I replace my battery??
Thanks in advance.
Edit: I sent it to service centre
Lol That must be my Z008?? which I exchanged with RN3
If you're rooted, check to see if anything is keeping your device awake for a long time with Wakelock Detector: https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en
I had horrible battery drain one day, and I looked in WLD and realized that Localcast was keeping my device 'awake' (screen off still) the entire time.

I've had the phone since Sept 6th and this is 4th day I have my phone.
My battery life has been draining like crazy. I don't have a data plan, but I do go on wifi sometimes (not very often, and I don't keep it on for long). Maybe in total an hour to two a day.
I wouldn't say I am a heavy user, I don't play any games or watch any videos nor listen to music at all. I only sms and download apps.
It's been 5h 42m 35s since unplugged and my battery life is down to 57. I hardly use it, my settings are pretty much the lowest.
It says
Android System 40%
Cell standby 21%
Phone idle 13%
Display 12% (weird, since I have animations are turned off and I used lowest brightness)
Camera 6% (I took 3 photos)
Wifi 4%
Maps 2%
Dialer 2%
about 2 hours ago, I rooted my desire since I've read reviews that it makes it faster, prolongs battery life and what not. (plus I could do so much more with it later on). But my battery was still draining at like 1% every minute and half that I touch it. (I also have task killer, but I don't kill task very often)
Then my friend suggested I get SetCPU (which I did) around 2 hours ago after I rooted my phone. Then I went out and hardly touched the phone unless I received sms, or to check the time. And it went from like 69 to 56 (within that 2 hours of doing nothing)
I've searched the forum for extending battery life (and googled as well) and read other users who have the same problem, and I pretty much did what was recommended but it's still draining.
I can hardly make it through the day!!
Is there any other way that I can charge it (when to charge it) or.. do you think it might be my battery's problem? Should I buy a new one?
Thanks for all the help again (I know this kind of thread has already been done, but that was in like April)
Your battery takes time to settle if it's a brand new device. It takes a few charge/discharge cycles for that.
If after say 14 days you are still getting poor life I'd try calibrating it. Instructions are HERE.
thanks! i will try that if my battery life still drains this crazily in a week.
I bought my Gnex from Handtec at the end of November. I have been very happy with it Until 2 weeks ago. Battery life has not been great but has lasted 16+ hours each day and I always charge overnight so this has not been a problem to me.
I take phone off charge at 7am. A couple of weeks ago I started to notice that instead of 50% at 7pm it was showing only 20 to 30% charge.
I bought BetterBatteryStats which showed no WaveLocks.
I started to freeze apps using Titanium Backup.
The battery life did not improve. I noticed the phone was getting noticeably hot to the side of the camera and charges were taking much longer. Instead of 3 hours it was taking longer than 7 hours.
Last weekend I noticed a drop of 70% in 3 hours on 2 occasions.
So I decided to wipe the phone and install AOKP build 15 with Franco kernel 10. I did not re-install aps. I charged he phone after install which took all night and then reset the battery stats.
The phone has continued to be hot and discharge very quickly. Charging is very slow. If the phone is off - charging appears to be even slower or not take place at all.
My Gnex is now fully discharging in less than 5 hours when idle in flight mode and is always very warm without any use.
I have been using a Samsung galaxy s2 wall charger.
Is this likely to be a faulty battery or phone hardware fault.
Any suggestions for next steps or is it a Samsung repair job.
Thanks

well, whichever it is, it sounds like a hardware problem that should be warrantied. i would flash it to stock and get it repaired by samsung, or see if the place you bought it will take it back
I get a similar problem but i return it back to vodafone 2 days ago and now waiting for the results, i returned it a week ago and they only give me a new battery to see if that will solved the problem but nope it persist, now they too it for either repair or replace ....

I am on the same build and recently used francos kernel. At night the phone would drop 20-30% of battery on airplane mode. Installed the apex build 5 kernel and all the battery nonsense stopped straight away. It seems to be a great kernel especially with AOKP B15.
Hope that helps.
Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
My battery stats have improved greatly by turning off location completely.
Took it off charge at 6am and with heavy usage
YouTube internet calls etc
still have 65% 16.5 hrs later.:good:
Just starting to play with battery use on my new G5. 100% charged 10 hours ago just before bed.
On a day to day basis i am a pretty light user. Calls and texts mainly.
Left phone unpluggged so it slept and 7 1/2 hours layer its at 93%.
20 mins music and email checking 19 hours in its at 88%.
Have Greenified much in the way of apps which i think improved things. Compared to the Sony i had the G5 seems to have ok battery life.
Its certainly in the useful, full day and better range.

Is yours rooted? I tend to get 5+ hours screen on time sometimes 7 which is amazing for a phone this cheap.
Same here, I have about 4-5 hours of screen on time with greenify, non-rooted. I'm a regular user, messenger, emailing, browsing, spotify etc. I'm also using Adguard which has its impact on the battery but a small price compared to having ads all over the place

Nope, no root as yet. And actually i may not depending on what ROMS become available in the future. Pretty happy with the way this is setting up and Android 7.0 stock. I think i may well leave it unrooted until after Android O hits and see where i go from there.
i'm rooted and the battery is very good, i got 7,5 hours SOT, usually i have 5-6 H of calls and 3H of SOT, 2 sims active, wifi and 4g always on, and the battery is 20-25% when i put on charging from evening to the morning. Very happy with this battery

Very good battery for price of the handset
I don´t know it´s a isolated case, but since i bought the phone, the battery is pretty bad, yesterday i tried to charge with another power adapter and my battery it´s lasting longer, anyone have this same problem?
Sometimes this happens to me.
When i keep my phone overnight(Battery Saver ON) even wid a charge of 60-70%, next day mrng, the battery is completely drained and phone is OFF. This doesnt happen daily, happens only sometimes. Any guesses why dis happens?
How is your Z play battery doing?Mine has got worse after 1 year used to get 8hrs plus sot now barely get to 5hrs
Share Your EXperience
I still can manage to get 8 hours of SOT. You should upload some screenshots of your usage so we can take a look.
I had the same problem, from 8-10 hrs of SOT to just 3-4hrs hardly. After some time of usage my phone used to heat a lot. Luckily my device was under warranty and after lodging complaints thrice they changed the motherboard and everything was back to normal.
on the first visit they told it was a software issue and reflashed the software(7.1.1) - No Change
I lodged the complaint again and they deduced that it is a battery issue so they replaced the battery - No Change
Now they told that it's a motherboard issue so they replaced the motherboard and now the battery life is back to the "Z Play" Calibre.
Mine is still the same as it was a year ago, i still get around 1 Hr of SOT per 10% of charge, give or take depending on what im doing. I dont do any heavy work with the phone just browse, text/phone and listen to music occasionally, that could be it as to why its still giving very good backup, or maybe because im still on 6.0 could be why.
The issue is 7.1.1 probably being power hungry. I noticed battery lasted less after the initial Nougat update.
It's a Google thing. Most phones last a lot less on Nougat than they did on Marshmallow.
On 7.1.1 i get 8h max of usage with 4G on and wifi, gaming and browsing. No fb,messenger,snapchat apps.
But on MM the battery life was way better: 10-12h of SoT with same usage.
