[Q] Battery drain issue

Hi.....
I am new on XDA.
Need help regarding battery drain issue on Samsung Galaxy I9103. I am using this Smartphone since November 2012 with default stock ROM and found it a good phone. No Root, no custom ROM flashed ever. But recently I faced the battery drain issue, sometimes it is worse. I change the charges as well to assuming that my charger is not charging battery properly but result was same.
I was about to change the battery. But today mobile is delivering outclass performance again which is very surprising for me. Last day I charged my mobile 3 times and every time battery drain out so quickly on idle / stand by mode.
Last night I charged the mobile about 65% and switched off. Then in morning I charged it again while mobile was still switched off and unplug the charges when battery was around +90%.
Question
1. Whats wrong with mobile?
2. Should I change my battery?
3. Any other issue.

the possible reason cld be,
1. some backgrnd process running constantly
2. device not going in to deep sleep when screen is off (requires root to check )
3. cld be a faulty charger or faulty battery in worst case scenario.

Hello
Good day.
Please review yesterday performance image. Most important, when I gave nap around 7-8 hours to my mobile, it is delivering good battery backup.
Further I was searching on net to regain Li-Ion batteries for smart phones and got following. Kindly validate this method.
Disclaimer: This should be used only if you believe there’s been an obvious decline in your battery life.
As promised – here is one method for bringing trusty dusty back to life
1) Turn your phone on and charge for 8 hours or more
2) Unplug the phone and turn it off, then and charge for 1 hour
3) Unplug the phone turn it on wait a couple minutes then turn it off and charge for another hour
Your battery life should almost double.
The logic behind this method is that your phone runs on battery power all the time even when its plugged into the charger. One side of the battery gets charged while the other side is keeping the phone on. So…if your phone is on while charging it never gets charged 100%. Doing this once or twice a month should recalibrate the battery and bring it up to full usage.

[Q] Battery crash?

Hello,
I bought this phone a month ago. At first the battery lasted quite well, I got around 5 hours of screen time with battery life to spare. Unfortunately, about 2 weeks ago I accidentally left the phone under my pillow and fell asleep on it- causing it to overheat a tad bit (I woke up 3 hours later and it was very warm to the touch and had turned off). After charging it up, I continued to use it normally but noticed that the battery would drain a little bit quicker than normal. Before I could easily go around 10 hours with heavy use and have 40% battery left, now after 10 hours it's left with about 15-20%. I am a heavy user but I haven't properly checked how much screen time I'm getting now, however I'll update that later.
As for the main problem- last night I charged my phone before sleeping (100%) and when I woke up in the morning it was turned off. I turned it on only to see that my battery had drained to 0% while on standby all night- whereas overnight I usually only lose around 2-3% battery.
After charging my phone up for 15 minutes- the battery level again returned to 100%. I only charge my phone through my laptop via USB. What happened here? Is my battery deteriorating? Should I get the phone replaced? I would appreciate any input on the matter. Thanks.
Also I've attached the screenshots showing how my battery died and how it was quickly restored. Can someone explain this occurrence?

Your sudden battery drop has nothing to do with what happened before.
Several people already mentioned this sudden battery drop as you can read in this thread, http://forum.xda-developers.com/showthread.php?t=2545553 and http://forum.xda-developers.com/showthread.php?t=2678909
No reason to return your device, its a know issue.

Drain your battery completly then charge your phone to 100%, turn the phone one and leave it to charge a hour more. Essentialy you have to recalibrate your battery.

So a brief update regarding SOT.
I left home with 90% charge this morning. Used the phone for 8 hours and it went down to 20% - granted, with heavy use.
Got 4.5 hours of SOT. Is this about average? imo I feel like this falls a bit below average. Ill check other threads as well and compare, but as far as I know, I feel like I should be getting a *little* more juice out of my phone. Data connection was on throughout, and some games were played and pictures taken.
Anyone else feel like they're getting sub-par use out of their battery?
*screenshots provided.
- checked the other threads, looks like ~5 hrs SOT is the most this phone puts out?

Same here.
Are there any news from Motorola?

Z3 Dual battery levels jumps arround..

Hello everyone,
I've bought an used Z3 dual couple days ago,and after having it for some days now I noticed that the battery jumps around,for example from 88% to 50% then 32% then goes back to 88%..
That usually happens when I'm running heavy apps,like camera which caused a phone overheating as far as I noticed.
Anyways,Yestrday I fully charged the phone and when I plug it from the charger it does down to 50%,it stayed at that level for almost 24hours.Few hours ago the phone suddenly the phone turn off (while the battery was still 50%).But After putting the phone in the charger,the phone keep showing "charging icon" and turning off.It was like this for 30min and it is not charging at all..
Have anyone been in the same situation before ? What could be the problem ? and how would I solve it ?
Waiting your kind replies..

That sounds like the phone battery is literally dying.
Don't think that it is a software problem you could solve on your own.
You could try this though, doesn't hurt if you do the Method 1:

Battery drainage problem.

Hi,
i am using s7 edge for 1.5 years now. Suddenly for the last 2 days my phone battery started draining very fast. It reached to below 15 in 2 hours. Then i decided to fully drain the battery. But shockingly the phone was working for houra on heavy use at 1%. Now whenever i am charging the percentage is directly going to 1% in minutes but not switching off. Please helpz

I am a beginner to Android Phones I should say first up.
However, my first suspicion is that your phone might have been hacked.
Search out how to detect illegal activity by third parties on your phone. Also, check your phones CPU activity if you can.
(I will do the same and post back if I find anything).

Question Phone is off, but battery is still draining

Is anyone experiencing a battery drain even though your S22 Ultra is switched off? I'm experiencing 4% drain every hour. 32% when every night when I sleep with my phone turned off.

I turn on power saving and extra dim using the bixby routine for the period that I'm in bed sleeping. It loses 1-2% ph

If you don't mind, can you try turning off your phone for the night and see how much battery percentage it loses? Mine went from 32% to flat 0% by morning. I had not realised this until recently. I tested in the morning by turning off my phone for an hour, it went from 60 to 54%. That's like 6% in an hour. But if I keep it on standby , it'll be 1% down in an hour. It's the turning off that is causing problems.

I know some laptops will drain battery power after shut down, but phone?

Exy or Snap?
Try checking in details with a battery monitoring app (e.g. GSam) to see what is/ are the culprit(s).
Also take a look at here for some useful tips.

It's strange that a lot of battery drain when phone is completly off.
In my opinion it's short circuit or battery is fault.
If phone is normal on are you see too battery drain?

When phone is switched off battery shouldn' experience any drain, or at least any noticeable drain in a short period.
Remember, when you bought your phone it came with battery half charged, and that was probably months after it was assembled and sealed in its package..
You should take your phone to a service or replace it, if possible

maybe somewhere on the PCB there is a short circuit. I ran into the same problem when using Xiaomi Mix 3 11 months ago.
