Z2 temp/battery issues - Xperia Z2 Q&A, Help & Troubleshooting

Hi,
I've owned the z2 for a year and a week. Unfortunately my warranty is up. The phone worked great this whole time except the past day I dropped it at work. Picked it up, no damage but the phone was off. I had to hold the power button and volume up to get it on. Since then the phone will discharge in about 3-4 hours with zero use where as the day before it would last over a day. After charging it for 2 hours, it maybe goes up 25%. It runs 58-65 degrees in safe mode. And idles around 48-53 degrees. So now after the drop, it runs hot, discharges quick and takes forever to charge. No updates were done so I can rule that out. I was thinking about opening it up and getting a new battery, not sure if that would be the problem. Any ideas?

Battery stops charging

In the last week or so I've had an issue getting my phone to finish charging.....it charges to ~90%, then stops. If I hit the home button it finishes charging within 10 minutes. I've left my phone plugged in all night and woke up in the morning to find it charged to 90%, then in 2 minutes it says it's done.
I would normally just shrug it off and say well I guess it thought it wasn't done for some reason....however, I've noticed that if it doesn't say 100% when I unplug it, it's dead with about 3 hours of constant use, instead of my normal 5-6 hours of constant use.
Does anyone have any suggestions? I do really abuse my battery, given it's almost fully dead and charged 5 days a week....should I just buy a new one on ebay???
Rooted X10a flashed to global 2.1 well before these issues arose, and no new apps installed or changes made from the time my battery was acting fine until this problem arose.
The problem with X10 is when the battery is fully load the devices will cut the power- stop charging . So in the morning you got approximately that much.

Battery issues part 2

So the original battery in my phone.. well... sucked. When I pulled the phone off the charger it would jump down to 93% no matter how long it was on the charger etc. Any attempt to bump charge was thwarted in the fact that I cant charge the phone when its off (it automatically turns on and boots into CWM). Wiping the battery stats when the battery read 100% in the OS would still result in the above.
So I ordered that 1600mah battery from Seidio. Ran the charge out of it yesterday and charged it to full during the evening/night. Wake up this morning, pull the charger out of the phone, and BOOM 100% power. Not 93%...
So was it my old battery that was bad or was there something wrong with how the phone saw its power rating?
From what I've seen with the phone, it drops down to 90% or so before it starts charging again, but it won't ever have the display show a battery decrease while plugged in.

Right but I can watch the meter go all the way to 100%... pull the plug and it goes down to 93% within seconds.
funny thing phone did the same thing...took it off the charger this morn and it dropped down to 95
I'm at 99% after about 2.5hrs of mostly idle usage. I've been just rebooting the phone with it on the charger in the morning, give it about 15-20 minutes and usually it'll stick at 100

All you are doing is semi-bumb charging it, which is fine if you really must have that extra 1hour of battery, but be warned, doing it constantly will damage your battery over time. that is the reason the phone has built in charging/decharge in the first place.
The reality is if your phone is sitting idle, that 5% wont matter at all once your phone attunes to your battery, and if your using the phone so heavily that your going dead long before the day is done (after attunement) then the 5% still wont matter !
i was having the same issues - 90% right after unplugging. had to charge the phone 3 times in ONE day and i never even touched the phone the whole day except to check the battery percentage.
brought it into verizon, they gave me a new battery and now it lasts me the entire day. when i pull the plug out now, it drops steadily like a normal battery should. i tried bump charging before i brought it in and it didn't help at all
The same thing has been happening to my dads Thunderbolt.
He charged it overnight, took it to work and was losing about 1% per minute without touching the phone. The only time it was touched was about 1 timer per hour to take down the battery percentage for his log.
He took it to the verizon store and they told him he should not expect anything longer than 4 hours of battery life without touching the phone..what kind of BS is that?

I'm having the exact opposite problem with the batteries--just ordered two of the 1600 Seidios that delivered yesterday and even after running pretty much down, fully charging overnite with the T-bolt powered down, drops to 95% immediately. Conversely, the OEM battery would stay at 100% for hours if the phone was idle (screen off / receiving any emails and SMS). Go figger.
There is a post in the Android Central forums on the 1600 battery compared to stock. After testing, they found that the two perform almost identically. Basically, it isn't worth replacing unless you go with the big HTC extended battery. Although having a spare isn't a bad idea. If only that battery door wasn't so tough to pry off when you need to change it...
nexus s had the same problem its nothing big though

Most of us probably won't have the phones long enough to see any possible damage. Starting off at a full 100% is a lot better than immediately dropping to 95 or so after pulling it off charger. It's kind of like the gas gauge in my truck. Stays full a while but once it moves off of full you can watch it drop. lol

Battery draining...

I recently exchanged a new 3vo after having some dust issues under the screen. This new one is pretty good with keeping dust out but there is a problem with draining the battery even when it's a sleep.
It's been off the charger for about 3 hours after hitting 100% and it's down to 92% after sending a few texts and sleeping throughout most of the 3 hours.
I'm getting worried there's something draining the battery, or if the unit itself is having issues going into sleep mode.

Did you check your uptime/awake time? I usually get 18+ hours of light to moderate use of my phone, I mean, there isnt much to do with the phone because I cant flash stuff yet. I have had two instances, which were odd. I put the phone on nightstand at 100% and after 6 hours my phone completely drained and shut down. Had this happen twice. Cant reproduce it, but I'm sure it'll happen again.
Yeah I checked my awake time and then let it sleep for about a minute. It took about 20-30 seconds to fully stop the awake time after the minute passed. There was an instance where it seemed to not sleep at all.
I don't know if it's supposed to do that.

My battery has lost its mind

So, I'm not sure what is happening - my phone battery is all over the place.
It started about a week ago - I'd see my phone battery at let's say 51%. We go out - take perhaps 2-3 pics, and my battery is down to 2%. Mind you - I haven't used the phone until I took it out to take the pics. Data was turned on, but no GPS or Bluetooth, no phone calls, nothing. From 51% to 2% in a matter of about 3 minutes or so. Then it dies - I plug it into the charger and it shows 26%. It charges upto 28%, we get out of the car and I unplug and take the phone with me.
When we get back in the car, plug it back in and it shows 74%. Doesn't change from 74 for a good 15mins and then goes up to 76% by the time I get home about an hour later.
Restart the phone at the 76% and within the first 10minutes it's dropped to 38%.
This has been the pattern, give or take, the last week now. I have no idea what's going and why it's happening.
I have not installed any new apps in the last month, and the phone is not rooted (G925I).
I have also tried to let the phone charge to 100% once it's died and then within 3-4 hours, the battery is dead on minimal usage.
I am not using the charger that came with the phone - am on travel and have a smaller travel charger, but this has never been an issue with the same phone before.
Any and all help is very much appreciated.
Thank you in advance!

You should probably use the samsung warranty because that is not normal

Same thing happened to me yesterday. I used tap tap shortcut to launch camera and shot few pics, videos. And then after maybe an hour without using my phone (no data, no gps) i looked at my phone and it had 1% battery left then it shut off. When i got home i plugged charger and after 10 minutes battery was 65%.
As for my situation I guess it's related with camera. I didn't exit camera app, just locked my phone using power button while camera was open and this happened. It's the first time that i'm encountering this, so it's hard to tell. Btw i'm using xtrestolilte 2.4.
I got the same kind of issues. My battery is crazy, I let it with Wi-Fi only, no Sync, no download and it lose 7% in an hour.
Sometimes I may just be on twitter and it looses about 2% every 5 minutes which is CRAZY !
Also, last time it turned off because I had 0%. I tried rebooting and it was at 10% xD.
Samsung did a terrible job with the S6, I don't know what it is exactly but it's weird.

New Update Fit2 - Battery issues?

Just received an update for my Gear Fit 2 today. and the battery is about to die after less than 6 hours of usage other than overnight sleep. And by usage, I mean strapped to my wrist as I drove to work, walked up 2 flights of stairs, and sat at desk for a few hours. Typically I wear the device for about 14-16 hours a day, throw it on the charger for about an hour and a half before I go to bed to top it off (usually about 70% or so when I put it on the charger). It will have 100% charge when I go to bed, and in the morning will be around 97% or so, falling to around 70% by about 22:00.
Has anyone else received this update and had any battery issues? I realize the update process would have likely used a few %, but my Fit2 is literally at 8% and it's not even noon yet. I was shocked when I got the alert to turn on power saving. Hoping this is an isolated glitch and will be OK tomorrow after I charge this bad boy back up.
And just to followup, after being in power saving mode for roughly 30 minutes, it just died. From 8% to nothing, while in power saving mode, in a half hour.
This happened to me yesterday after I just installed the update, it went from 75% to 13% in just 4 hrs. (I must say I had debugging and Wi-Fi on during that time as I was testing some watchfaces) I just charged it this morning, and it seems to be fine, again.
Well, after charging the initial quick discharge, I charged it fully and all has been fine for a few days now, so must have been a weird fluke. Odd, but not the end of the world.
I found that my fit 2 can last 2 days max with wifi off after update
I got same battery issue too
I had the same issue, AND it started havingHorizontal lines across the face, three to be exact. I believe the watch itself has a display defect, as I have found dozens of similar reports. I returned mine to Target. Thank goodness for the Red Card return policy is all I have to say. I have some armorgear shields and a leather watch band if anyone needs them LOL Considering getting the old gear fit and using some of the alternative software.
