I have had my N7 for a few days now (fully rooted using Buttered AOKP ROM and ElementalX 1.8 kernel). I have a US power adaptor with a UK adaptor. I have my N7 charging all night but it doesnt seem to go all the way to 100% - it gets to about 96%. Is this a known issue? Is it worth returning/exchanging the unit?
I bought it (£170!) new from play.com.

It's an ElementalX feature (battery life extender). Please read about it in the appropriate thread.

Had this issue with CM10.2 (nightlies) and it was a pain since I didnt feel the battery extended. Was on glitch kernel. Not sure if that was the issue or the ROM itself

It's not a feature to extend the battery life of the device as in how many hours you can use it off the grid. It is a feature to extend the battery life as in how many charge cycles is the battery gonna last. It has been shown that if you drain a battery fully and recharge it to 100%, you put more strain on it than if you let it drain to 20% and charge it to 80%, that way you increase the usable charge cycles by a lot. That's what that feature is supposed to do.
My n7 has not been charging fully either. I am using the stock charger and I'm running PAC ROM for about 2 months but this just started happening. Idk why. This picture is after I had my tablet plugged in all night while charging

mine usually takes 3 hours.
the thing is if i touch it and turn the screen on and use it for awhile, i notice that my battery % isnt going up. it just stays to the % where i start using it, even for 30 mins.

I read your thread earlier and let my phone shut down by itself then charge it while it is turned on and most of the time DayDream is also on. It is about 1 hour and 50 minutes to be fully charged. I do not remember it ever exceeded 2 hours unless I am playing a heavy game while charging.
I am running my own AOSP ROM and trinity kernel alpha 7.
A similar thing happened with me when I had my S II. The percentage holds and does not increase, but if I reboot the phone then it shows that it was really charging. For example if it stopped on 45% for some time, then after reboot it may show something like 75% immediately. I think it was a ROM or kernel problem, so try another combination and see if your problem is fixed.
Hope this helps

As I mentioned, my problem was related to ROM and kernel on my S II, so maybe you would like to use another ROM and kernel then check if this problem is fixed

If you do a full wipe (system, factory reset, cache, and dalvik) and install a fresh ROM, does the slow charging and inaccurate percentage exist as well?

Is it a problem with the charger? If it's a third-party charger, maybe it doesn't deliver enough juice. If it's the mfg's charger that came with the phone then maybe it's dying on you.
Doesn't anybody use math? The stock battery (1750mah) will charge in just under 2 hours on a 1A wall charger assuming you leave it alone to charge.

I charged it from 38% and it took about 1.5 to 2 hours. It has an upgraded S4 Pro like the Nexus 4, so I assume it has the quickcharge part of the SoC that the Nexus 4 has.

I'd say it's some kind of issue. I get better than double that speed charging with the included cable. Might want to see about swapping that for a different one.

Hello,
I bought a gently used N900T a few days ago. The device is awesome and works perfectly, except for one thing. Charging the phone with the Samsung charging cable+ac adapter takes longer than forever. It charges at a rate of approximately 8-9% per hour.
A few notes:
Device on, device off, it doesn't matter. It charges at the same slow rate.
The battery itself, once it charges, holds that charge very well.
The slow charging happened both when I was on the stock rom and on my current Slim Rom.
I have ordered a new charger and a new battery. If the slow charging persists with these new accessories, am I doomed? Is the slow charging a known issue for the Note 3? Besides the new equipment, does anyone have any advice on how to solve this?
Thanks so much!

I am using a genuine Samsung Note 3 charger. The replacement coming is another genuine Samsung Note 3 charger. I'm sincerely hoping the one I have now has a cable problem or something. I really, really like the phone but I'm wondering if anyone else has seen a similar story or knows of a possible solution in the case that the new charger+battery do not work.

Well I have to be honest from dead it takes about 2.5hrs to get back to 100. On stock.using the wall charger with 2amps. When he gets his new charger he should be good or a good kernel swap. Either way it should come back to normal

I got a new charger and it's still charging at the same slow pace. What could possibly be wrong with my phone? The battery holds a charge, the phone works near flawlessly. I'm dumbfounded.

You gonna have to do testing or replace phone. Me I would change kernel just cause it takes 2 seconds. Let it ride a day if no change then a factory refresh. You have checked that no app is killing phone as fast as it charges right?

Edit. I was just on his thread and a few guys having issues with either bad batter. UV/ oc .try a different ROM and kernel. Fresh install meaning Odin back to stock and start all over. Sorry good luck
As weird as this sounds, I tried the charger in a different outlet in my home and it works a lot better. The battery charges quite fast from any level to about 96%, then starts crawling again to 97, 98 and stops at 98. I opened battery calibration, which shows the battery at 96% and 4337mv, which is the same mv level as 100% normally if memory serves me correctly. So I'm thinking the battery is "full", but for some reason won't go to 100% without a fight. Perhaps if I clear my cache+dalvik cache? Any other suggestions?

What was wrong with mine it was the charger. The usb wasn't connected all the way in the AC therefore was only charging like it would through computer as soon as I fixed it with a blow of air and a gentle push it right away started charging AC phone charged in 2 hours
I could be wrong but I noticed my charging is slower when I stick my charger into a surge protector power bar as opposed to a standard wall outlet.

A couple of weeks ago I got Cyanogenmod on my Tab, from that point the battery life has been horrible, the battery percentage goes down by the minute and it goes down when I'm using it while charging too! This is a huge problem for me because I'm always using my Tab Pro. I want to know why this happens and if I can fix it.

A few things to check.
You really do need the 2.1A charger, not a 1.5A charger, if you hope to charge while running.
Ensure under Settings - WiFi - Advanced that "Keep Wi-Fi on during sleep" is off.
Ensure same area "Scanning always available" is off.
CM seems to have a problem with Exchange servers, so if you're syncing to Exchange, change from push to polled.

Samsung Galaxy tab 3 7" SM-T210R. Recently my tablet has been having problems charging. Like when I plug it it it takes forever to charge. Before I could use it and it would also charge. Now when I charge it and use it, it stays at the percentage it was at when it began charging. Sometimes when I unplug it, it'll be lower than before. When I put it on charge over night (6hours) it'll get to 100%. I'm still using the original charger that came with the tablet. Any help would be thanked.

Exactly have the same problem, I'd like to ask first, are you rooted? What rom are you using? Because that could be the issue, I'm rooted and I'm using nolekat rom. It takes me 10 hrs or more to fully charge and it drains half the time fast. The percentage on the battery jumps higher then goes lower and it decreases while I'm charging and using it and I'm not doing anything heavy. I already tried using the battery calibration app which most people recommend to troubleshoot first, it didn't work for me. I suggest that you try calibrating first and if it doesn't work, reflash your current rom if you're rooted, if you aren't, it could be your charger and I also know my charger isn't faulty. Last thing I'll suggest is try manually removing your battery for 5mins then put it back in. I haven't tried that yet, I need the tools still. Hope this helps and let me know what you've done.
