battery only chargers to 95% ?

Is this normal. I did try and do a search in my defence.

Yes. It is like that by design. It stops charging at around 95-98%. Its to prevent you from overcharging the battery.

This is a known issue. You can try and reset battery stats in cwm when your battery is charged and/or emptied. It works for some and not for others. I haven't noticed my battery lasting any less when my battery doesn't "charge" past 97%

There have been some discussion on this. I get about 97% myself. From what I've read you may get full charge if you let it drain all the way. I don't do that myself. Very happy with battery life as is.

I used to get 100% before I switched to the Vegan rom.

Either let it drain until it shuts off a few times and then charge it all the way up or if that doesn't work, use CWM to delete the battery stats when it's at 95% (full, with a GREEN light - not charging, with a red light) and then let it drain until it shuts off on it's own.
I did this a long time ago (delete the stats) and it's been perfect since. Charges to 100% and does indeed show battery at almost empty before it shuts off.
Good Luck.

Still no go here but it can get tom 96%... lol

I am sitting a 98% with VEGAn.

I am now having an issue where u can use the device, then I turn it off, and
turn it on the next morning and see about 5 to 10% of my battery was drained.

Confirmed Fix
Confirmed fix for me on Vegan 5.1. Letting battery drain down to zero and shutoff the tablet... reached 100% on next charge. Now the indicator charges to 100% every time.

tried this and still no luck . still get to 95-6% bugger

Vegan here..this is how I fixed it:
1) Drain it till it shuts off, try restarting it a few time to make sure its dead.
2) Once dead, plug it in, boot into clockworkx, and reset battery status (do this quickly)
3) restart, and leave plugged in idling till fully charged
4) use and enjoy a accurate battery level!!

You have to remember that in order to install some apps out there, you have to give them permission to use the internet and to interact with your device autonomously. I have found a few apps that were pulling my tablet out of sleep mode and turning on the wireless to download ads or other updates, and that (along with the length of time to shut back down) was affecting my battery life.
I would say to go back and review what you've installed, and to also check your screen timeout settings. Just doing that saved me quite a bit of overnight battery loss.

Easy steps for battery life preservation

This is not a guarantee of battery life extension or performance. These are merely steps (in most cases) to possibly help prolong and restore battery longevity.
First lets understand something about battery charging. The most common mistake is to overcharge a battery. While one is inclined to charge when they see the low battery message, overcharging is detrimental to the battery. This is not good for the life expectancy of your cell phone battery, especially if you are expecting longer life from your battery. Over charging heats the battery, and drains its life expectancy.
Second, it would appear that after flashing (ROM’s, Kernel’s etc.) multiple times, your battery might not hold a charge all that well. Trying these steps may help improve battery life.
> Turn the phone on. Plug in the charger (not the USB to computer) and charge completely> Disconnect the charger and turn off the phone> Once completely shut down, plug the charger back into the phone. Let the phone completely charge, while phone is off. In some cases the phone may give a tone when charged. You can check its status by touching the volume up or down> Once again unplug the phone from the charger> These next steps are curcial. 1.Turn the phone on (give it time to boot completely) 2. Power it off again. 3. Connect to the charger once again. 4. Let charge to full one more time. Unplug the phone!
In most cases, this procedure need only be done once. Remember turn off bluetooth, intranet and other applications when not in use. These accessories pu a tremendous drain on a cell phones battery life. This is why they should be turned off, when not in use.

i feel like i do this every time i recharge my battery because every time i charge to 100% then turn it off and plug it in, it takes another 5 min to charge to 100 while its off. Literally, every time i bump charge it.

Mhmm, an explanation of the bump charge. Been written here before, but eh. Maybe someone lost theirs. I lost my txt file with the instructions a while back lol.

The way I see it these instructions only help to provide a more accurate battery count. Whether the battery is displaying correctly or not, juice in the battery is juice in the battery. Nothing more nothing less. This whole battery issue is ridiculous.
I think it'd be a good idea to remove the battery icon from the notification bar all together.

No. Your phone has software in it to detect how much battery life is left for a variety of reasons; it turns more battery-intense functionality off at 5%, the camera for instance, and keeps enough battery power so that it can run its shutdown procedure, instead of just dying and losing whatever's in memory at the time.
You also don't want your phone thinking that 19% battery is 1% and turning off or telling you to charge it, as charging a battery that isn't fully discharged is a great way to lose long-term battery life. Additionally, how much would it suck if your phone software thought that 75% was 100% and stopped charging? You could then be leaving for the day with 3/4 of your battery, thinking it was full.
There are plenty of reasons to want this to be as accurate as possible. Unless you just don't give a crap if your phone is usable or not

I was having all kinds of issues with my battery draining too fast. I unplugged at 7:30AM and by 10:30AM it would be at 60%. I tried the bump charge and all that, but then I realized "It's the apps, stupid!" I started running a task killer after I unplugged it, and now I'm making it to noontime and I'm only down to 80%.

A few days ago my phone shut off after draining the battery - before it shut off the battery was less than 1%. i let it sit for ten minutes or so then turned it on. - it showed 16%.

i do this ALL the time!

If you are running a custom rom it is also good to delete the battery charge stats when booting back up after step 4. If you have CWM just boot into recovery, go to advanced, then clear battery stats.
There is a way to clear it if you don't have CWM, but I don't remember what it is and I think most people have CWM anyways.

I check my apps frequently. One day my weather widget was going nuts and was using GPS non stop. I pulled my phone out at lunch and the battery was in the yellow. Granted I haven't seen that happen again it has made me reconsider even using apps/ widgets with GPS

widgets kill battery. I had several pages of widgets and I had to wipe by phone, remarkable how much "better" the battery was after that. Weather widgets look great but it costs to run them.

I've a feeling it has less to do with the actual widget and more to do with their constant updating when there is a poor or nonexistant connection.

Don't download the anaimation sub-app. update on the hour (or 2) instead of 15 -30 min.

I would love some advice as a noob here. I've only had my Cappy for a little over 2 weeks. I've done the battery calibrate trick, but still don't see very good battery life. I unplugged from the charger at 100% at 10pm last night and left the phone on all night. Wifi and GPS were turned off. Beautiful Widgets is set to update weather every hour. The phone received 7 sms messages during the night. When the alarm went off at 6:30am I was at 70%. It's 10am now, so it's been off the charger for 12 hours. Here is what I show:
Voice Calls 34%
Cell Standby 23%
Phone Idle 16%
Display 15%
Android System 4%
Beautiful Widgets 3%
Android OS 3%
Android Core Apps 2%
antivirus 2%
Battery currently shows 51% left

Would anyone suggest Advanced Task Killer or Juice Defender?

There are some good tips for prolonging and caring for your Battery here: (Can't post links, google search: site:arstechnica.com battery life ask ars)
However, cell phone batteries rarely run over $30 (I have seen capivate batteries as low as $13), if you just always fully charge it you will still see a good 8-12 months out of it, and then just buy a new one. $30 a year is worth it to me to just let the thing fully charge so that I can use it for longer.

PLEASE DO NOT INSTALL ANY OF THESE BEFORE READING
http://www.xda-developers.com/android/the-view-on-task-managers-for-android/
If you fully charge and run the battery, done several times, the battery will eventually run better. Surprisingly, there is a "break in" period for the battery.

I appreciate the advice on the task killers and such. I don't use one, and after reading that stuff, I won't. I pulled my phone off the charger yesterday at about 1pm. By the time I played some games, did some web browsing, made some calls and did some texting, it was still at 70% when I went to bed at around 10pm. This morning at 7am, I was shocked to find that it was still at 67%! I don't have a clue what was different. It typically hogs up 25-30% overnight, but this time it only did 3%. I wish I knew what was different. This is so weird!

Battery issue after 4.1.2 update

Recently I've updated my Note through OTA to 4.1.2.
I've spot that after update the Note is just draining the battery.
I could read about 10 hours on it before, and now it is only about 6 !!!!!
I even do not mention gaming, which is draining the battery in 2.5-3h from 100% to about 5%. I could play approx. 5-6 hours before.
It's ridicules.
Did any of you spot the same thing?
I haven't installed any additional apps after update that may "help" to discharge the battery.
The values above are based on Screen usage time in Battery menu.
Any suggestions?

After the update, I'm facing recharging issues. The tab is taking twice the time of what it used too to recharge to 100%.

i haven't spot any issues with charging.
.

Same here.Used to get 10 hours of screen on time,now i am lucky if i get 8 hours!

Same here...
Some tips :
Kill all apps, switch to offline/airplane, and power saving mode when charging..
Still not working?
Try reboot your device once or twice if necessary..
And your device will charge normally
Work on my gnote...
I hope it will work for you too
Correct me if i'm wrong

Im using juice defender with good results, I lost a pretty noticeable amount of battery time after 4.1.2, too.

Maybe a problem with the battery stats?
Try to drain the battery empty and full charge afterwards.

It will damage the lithium battery when you drain it till empty

I think it is Wi-Fi that drains the battery !!!!
Usually I was leaving the tablet with wi-fi on all the time. After 4.1.2 update it takes approx 2% of battery per hour !!!!!!!!!! when you do not use the tablet but wi-fi is on, so after night in the drawer you had approx 10-15% drained.
When I turned the wi-fi off and left it overnight i haven't loose even a 1% during the night !!!!!
I have to try to work on it as usual but with wi-fi turned off, it will be difficult though as usually i play on-line or browsing the net
I think they f#^%*d something in 4.1.2 update with wi-fi energy consumption. hope they will repair it in next update.

I mean, just let the device turn off by itself, and after that, charge 100%.

Yeah, I had this problem after I updated too. It was also laggy. I did a factory erase and now it works better. I think it is still draining more than before, but not as bad as after I updated. I think a good rule of thumb is to wipe everything after an update and start all over. You could also try wiping and flashing the rom for a fresh install.

I suggest you to change your rom to germany stock 4.1.2...
It will solve your charging problem

[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.
Battery usage screen shots attached in PDF.

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.
but i suspect reason 1 or 2.

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.

Rubbish battery life?

I got an S7 G930F yesterday, first full charge last night, I haven't it even properly set up yet, haven't got most of my apps installed yet. I took it of the charger this morning at 8am its now at 50% at 2pm, 45 mins screen on time with the biggest battery drain being android system 20%.
I have hardly used the phone today as I'm off work, at this rate it'll be dead long before bedtime with me doing nothing.
Any ideas?

Hard to expect getting the best of it at first. It took me a good week to figure out how to optimized battery without having to use it like a 2G phone. I suggest you do factory reset. Observe how it goes that way. For the first time, a handful of things run in the background; syncing, location, whatsoever so I bet it'll take a while to really adapt and I can assure you based on experience, it's like that as it was like for me.

Always takes a few full charge cycles to get the best out of a new battery I find, fully charge and fully discharge 4-5 times, calibrates the phone too to know what 0% and 100% are iirc
But you're always going to see high battery usage setting up a new phone, installing apps, screen on constantly, playing about with it more than you will once you've had it a while

The are wide reports today of crazy bad battery life. Some people are tying it the latest Oculus update.

I'd like to believe that but I didn't have this issue on my Nexus 5X with a smaller battery or Huawei P9 Lite, in fact the P9 Lite also has a 3000mAh battery and I could make it last 2 full days, this won't last 1.

Getting the phone yesterday, you've hardly given it a chance, with heavy usage I get just over a day with mine, with medium, 2 days
Same phone, same OS, same battery
See how you get on in a week or two, or return it and get the Edge, 3600mAh
Check the package disabler pro threads, disable the battery draining bloatware (no root needed)

Yep thats the usage I got with my P9 Lite with the same size battery. I was sitting this morning look at the phones always on display. 30mins of the charger it was at 94% and that's with me not even touching it.

It's crap for the first few days
Whenever I first got my phone or when I factory reset or when I install new rom, the battery life is usually crap. But after a few days when battery optimization kicks in (power saving on apps not used in past few days) battery gets tremendously better.

Posting back to confirm that Oculus update shat on a lot of phones.
Oculus home process kept trying to install and uninstall. This demolished battery life, increased heat, etc.
Once I uninstalled Oculus, all problems went away. I will reinstall after fix.

This may be caused by either the oculus app or good lock app they have been reports on the Internet about these two particular apps
Also when setting the phone for the first time it will drain battery in the first few days

Confirmed about Oculus draining battery

Definitely was, my phone overheated and shut down over night when the update came through. I literally couldn't charge it it with fast charger. it would just sit at the same % it was burning through the battery so quickly. uninstalled sammy vr and oculus apps everything fine now.

I don't have anything oculus related installed. The is day 2, second full charge last night. Of the charger now 1 hour, its got flight mode on with wifi calling enabled. I am currently at 90% with 1 min screen on time. Android services again the biggest hog but it contains IPSec services which does the Wifi Calling part.

I was about to remove Occulus when I received an occulus update, about one hour ago, and it seems that the problem is fixed. The battery looks ok, and the phone is not hot any more. I'm waiting a little bit more to be sure...

Right guys I have found the culprit of my drain issue. Wifi calling. I happened to turn it off and I have gone from 10% drain in an hour to 1%

That's more like it, never used WiFi calling so wouldn't know if it causes drain
EDIT - Not available with my model / carrier

There's a debloat script back in the Development Section which will remove all those trash that came with the phone, as for battery optimaztion This Ultimate Battery Guide is one of the best here in XDA and is a must see for anyone with an android phone basically
Goodluck
