I've had the Z2 two days now and I'm afraid my unit has a problem:
Even in normal use it gets really really hot in the back, on the upper left hand side.
Also, the battery life is really not that great, which is disappointing for a phone with such a big battery (it is barely better than my HTC One M7)
I have neither rooted it nor flashed it, everything is pretty much stock (I have disabled a few apps like facebook)
From what I understand, it is not supposed to be that way.
Does anyone have suggestions? I would prefer not doing a factory reset
Try to get a replacememt
It seems units made before mid may have commonly had majour heating issues, bugs,lag bad battery etc etc etc

Mine was made in the 18th week (end of april, beginning of may)
I'm not really keen on sending it back, as it probably means several weeks of delay, with the shop I got it at.

Well you dont have much choice
Either stick with these unsafe issues or get a replacement
If you get a perfectly good unit back, you wont regrett the wait nor replacememt
You will find that the Z2 has an amazing battery life, the Z2 ive had hand with has lasted from 22hrs to about 49hrs with moderate/heavy usage
Device just got warm, not hot

I'll have to think about it. I was hoping there would be software solutions for those issues (they seem related to me: something is working too hard, causing overheating and increasing battery usage)
Check for deep sleep and wakelocks if any.

Also try doing a factory reset. Mine doesn't get hot and battery lasts very long. Up to 2 days with light to moderate.
At first it was awake all the time, even with screen off, so I guess there really was a bug.
I now have factory reset it, left it overnight without charging it, lost 9%.
Is that a normal number?
I've attached a screenshot of the power management app. Can someone tell me if there's something wrong with it?
My overheat issue cam from Google image backup. Turn it off and see what happen.

Ok so im quite new to android so im not 100% on the ins and outs on how what uses what battery and when.
Im running skyrom v9 and my battery was crap. To be honest its never been good. So i tried speedmod kernel and still got the same results.
Now iv disabled lockscreen widget and seems my battery is much better so iv put it down to that been the killer.
Iv read some people are using this app with no issues. My friend tried it with the same rom and kernel as me and it was fine.
Question is are these phones like performance independent? Like will each device act and behave differently to different thing or shud one sgs2 be the same as another sgs2 that is set up the same?
Long winded but i got there

They're mass produced, they should be exactly the same. There may be really really slight performance differences. And tiny differences in screen quality. But this may depend on the batch.
What would be the case most likely would be the fact that you have a faulty battery. But it seems you were able to fix most of your problems by getting rid of an app.
There's a lot of things influencing battery life, dude! Every little thing you do and use can get the juice sucked dry in a couple of hours.
I thought as much. Just seemed odd. And although getting rid of that app seemed to work, its now gone back to its useual gonna die soon self. Gonna try another battery i think.

In a way they are all different .
Different users with different apps and settings plus a different and varied level of user intelligence . That means phone A can be poor for user ZZ but give it to user YY and its working well .

Well only thing i have left to try is battery. Im just waiting for my other to charge then i will swap and test it. Best i have had my battery is loosing 10% an hour. Which imo is a bad crack.
When i go to my battery stats it says cirtain apps are using x%. Some of the apps iv never ran. And some like maps for example is using battery. I stop the maps app and still its using battery. Why?

A good test is to stick it in flight mode and shut down as many apps as you possibly can. Then just leave it in standby for a couple of hours. You should really only lose 1-2% of your battery. If you do then you know something on the phone is responsible and you can start looking for and freezing the suspects.
I've had mine in standby for about 9 hours now (since I unplugged it) and it's at 91%, after only a few texts and emails. That's with data on most of the time and a little wifi earlier. I'm on 2.3.5 and KH3.

The phone is the same, it really is all in the user settings and usage styles. If you want to prove this, just reflash any ROM and kernel (they are not that different) and do a full wipe of the phone. Don't set up a Google account or any email accounts or install any launchers/apps/widgets. Use a plain black background/lockscreen. Just use the phone, SMS and other stock apps for a while. You should be getting around 3 days or more of battery life with moderate usage.
I've gotten 3+ days of battery life before, but nowadays I get less than 1 day. So when I read that other people are getting great battery life, it's not because their phone is different than mine. It's because I need to use Exchange for my office email, or because I want to run a certain widget, or have some extra notifications, etc. So all you can do is keep experimenting, updating, etc. until you find a combination that works well for you.
Can anybody explain to me why all of the sudden my battery life has sucked. I have had WolfROM for about two weeks and battery life was normal. Then around 3 days ago my battery just won't last. I don't know what the deal is. I did spend the week in the mountains of Georgia where it was constantly searching for service so it got really hot. I assume that is what killed it?

I would expect it to. In your particular situation, the easiest route to an answer is to put it in airplane mode for several hours and compare.
Also, if it really bugs you, get one of the apps the other guys have suggested.
Although it seems to happen less frequently, sometimes an app update keeps the phone awake.

On mine the download manager was using as much power through wake locks as the screen was. Disabled that ***** and turned off force gpu rendering in the developer options for good measure. It made all the difference.
My phone was over heating and losing charge extremely fast. I decided to try something random and put some of the aluminum off the back of a laptop LCD between the phone and the battery. It seems to keep the phone much cooler and the charge holds a lot longer. I can play Finaly Fantasy 3 now for a few hours without the phone getting hot anymore. Don't know if it will work for everyone but it seems to be working for me.

They wanted me to let them replace mine, but I told them to **** off. I'm not giving them a new phone for a refurb. That is one thing they could definitely use some improvement on. If you sell me a faulty device don't try to give me a refurb, give me a new phone.

Nah, the battery can breath fine. The insulating aluminum is actually between the physical phone (sim card and all the interals) and the battery. The battery is completely open on the back. The phone itself is also not getting hot anymore so I don't really know. It used to get so hot that the screen itself was hot to the touch and so was the plastic cover on the back. The battery actually has the paint missing in the pattern of the lines of the rear cover from being so hot. I am sure the battery is at least partially cooked but it made it a full 12 hours today on one charge, thats up from 4 hours.

Results are skewed for the day, I pulled the battery to replace the aluminum. I didn't have any scissors yesterday so I wound up with a rough looking piece of aluminum that I had to tear apart to make fit. I cut it to fit today so its a much nicer fit and it still has some adhesive from where they glued it to the monitor. I'll let it burn down all day tomorrow and post the stats. I had wifi and google maps running evidently though during that time. I know I talked for around an hour and a half on it and I was in the office most of the day with nothing to do so I probably spent two hours texting.

I had only been on WolfROM for a week. My battery seems to be returning to normal though. I guess some normal usage fixed it.
Being there's so much difference in battery life, I was curious if there might be a bad batch of phones. My phone gets great life and my dad's gets significantly less. He works about 2 blocks away from me and actually has a stronger signal in his building than I do at mine and his battery drops like a rock with nothing running. I'm rooted and froze the AT&T bloat. He's stock.
My serial number contains a PTM and the end number is in the 40000's. His serial number contains PZK and ends in a number in the 30000's. If you have time post your serial # info and how your battery life is.
I returned my ladies OG and now her battery life is better. Even b4 I rooted it drain was better from prior phone. Could be a batch. That's my lead as well

Resetting battery stats actually has no correlation with battery life whatsoever. It is not what controls the percentage that we see in screen. I believe it just tracks what apps or system files are or have been using up the battery. Battery stats gets an automatic reset whenever you reboot anyways.
For those with bad battery drain, just try and see what your serial numbers are n post it here to compare.

The battery life on my phone and seemingly most folks is great. Granted some folks probably live on the cusp of LTE coverage in their area and the radio is killing the battery while liking for signal (that happened to me with my EVO 4G).
If it were all devices, then only the battery life fanatics who shut down everything would be seeing 20hrs on a charge.
I think there's a bad batch of hardware or there.

my s/n: KPUU 40000's the high end. I dont think its a batch.
seems odd that those who are having the issue are not likely to make to 10hrs on a charge (often 1/2 that)...while others are bumping 20hrs (myself included).
i have 4 emails on constant sync, as well as, facebook, weather, xda and a chess. each day has a couple hours of screen time. 1hr each day of either Pandora or Audible. 20-50 text and @45min - 1hr of phone time. ... in case you think i put my phone in my pocket and forget about it.
granted, i do connect to wifi at home and work. and i live in an area where i have solid LTE coverage at all times.
audible and screen time are my worst battery drains.

We got ours off the box. Not sure where you'd get it in the phone.
Did a little more research. Set them side by side for an hour with screens at same brightness, always on, with Nexus live wallpaper running. Both were hooked into wifi and the microcell. Battery usage over a 1 hour period was pretty much identical (within 1%). Then did some web browsing and hit all the same links and drain was the same. We thought it maybe was just battery conditioning. When I first got it I did 2 full drains and recharges with it off. He did that about a week in and thought it was fixed.
I left and a couple hours later his battery started to tank. Only thing we noticed was his accelerometer hung for some reason and had 5 hours on. He hadn't used anything that should have turned it on so no idea why it got stuck. Turned it off and the battery usage slowed to what one would expect. Then it had another couple minute burst of dropping. that was the last I heard.

Eh, what can I say, most battery monitors out there are horrible at keeping track of things, something you may have noticed if you have a laptop. Android's battery monitor is know to be absolutely worthless, and it lives its own life.
Remember that it takes a couple of charging cycles to get it back on track when you flash ROMs. And you should probably enable STAMINA if you had horrible battery life before you flashed. There's probably an app that has gone rouge, so check your data usage and download a wakelock detector.
Sent from my C6833 using Tapatalk
What previous poster said.
Flashing ROM's is not the way to fix inaccurate battery reporting. It will probably just add more to the confusion as flashing ROM's is usually the reason for inaccurate battery readings.
What you need to do at this point is to run the phone completely dry once so it dies and then fully charge it. Then it should be fixed right away. Otherwise just let it be and it should be fixed in a couple of charges. Remember that running the phone completery dry too much aint good for the battery. Though they have built in protection so they never get completely dry. The real dangerous thing is to leave the phone totally dry without charge for longer amounts of time. That surely will damage your battery.
Yeah I had use stamina. It was weird sometimes I could get 6hours screen on time and other times 3
I downloaded wake lock detector and there was a wake lock that woke up the device over 20000 times. It seems to be gone now after re flashing.

You'd enjoy using the HTC One X then, normal use it easily reaches 42ºc, extended use and/or heavy use can see the phone reach 55ºc so for me, that's a welcome change.
I should be receiving the Z2 tomorrow anyway so I'll post my findings then.

Water resistant coating will always trap more heat inside, maybe that's why Sony uses the slightly lower clocked SD801.

I think that would be a reasonable assumption.
I guess the only question is whether it's a deal breaker or not.
Does increased temperature effect battery life at all?
I noticed this happening recently but on rare occassions. It gets hot right where the camera is located but I'm not sure if it is related to the camera or some other app. I know that it overheats when recording 4K videos over 3 minutes. The quick fix when it heats up is to restart the device so to me it is definitelty software realted.

Coming from the Galaxy Note 2, when my phone got warm it indicated that there was a problem. Maybe since this is part of the design, with the waterproofing at all, I'll just have to learn to accept that the phone will get a little warm.
On the plus side, it'll be good for the winter, to warm up the hands

Does increased temperature effect battery life at all?

Most definitely.
Well i can asure you that all snapdragon 800 soc overheat and it depends on what you do,my curent device lg G2 when i bought it,it had jellybean on it whne browsing web listening to music etc it always got hot,but when plating games it was a very big overheating ,the procesor got up to 72`C ad baterry was on 42`C and i thought it was a problem with the phone but after updating to kitkat all problems with overheating where gon even in graphinc intense games it took the phone 30 minutes to heat up significantly + on a side note the battery got a lot better i managed 4 hours and 36 minutes of screen time.
Botom line its a software problem coupled with the nano coting(it blocks heat but not in a bad way that the phone will overheat from that maybe a 5`C block).
Overheating is the reason I didn't get the G2.
It overheated doing basic stuff.
It can't be fixed by software. LG certainly didn't release a fix, so don't expect one for the Z2.
When a phone has overheating problems then it will always have it, just like a laptop or any other hardware.
You'll have to deal with it.

Well not really my m7 used to get warm / hot with 3g or gaming up to 42c after sense 6 it refuses to go above 35c and when gaming up to 39c , so far only known phone that doesn't get hot is the m8. Imo it's tolerable for z2 to stay warmer then other devices , glass isn't the best option for cool phone + sealed phone due water resistance.
Btw yes warm / hot phones have shorter battery life due heat issues , warmer battery = faster discharge rate.
Imo if z2 gets hot only when gaming it's fine, all phones get warm but if it's crossing 37/38c up to 40+ on WiFi and normal usage I'd call that a problem. You can forget the gaming if this is the case lol , at least stable gaming without fps loss and throttle.
The overheating when using the camera is a bit of a concern, especially since that was one of the main reasons i bought the phone.
Is it definitely software related or hardware?
As if its software i can wait for a fix, but if its hardware then i'll need to swap phones
After reading other device forums seems like all the Snapdragon 800/801 devices have the overheating issue: SGS5, Z2, G2, etc.
I think it's because the new SoC is so powerful that it generates a lot of heart, especially when gaming.
Maybe the 805 will fix this. Not gonna buy a device with 800/801 because almost all of them have overheating issues.
