Forgot my phone in the sun

Hey guys, I forgot my new sexy white Gnex in the sun a few days ago. It got so hot that I could barely hold it in my hands I'd like to know what damage could there be from this overheating? As far as I know, heat kills lithium batteries really bad. But what else should I check?
This is the battery life I get since this happened ( no data active, just occasional small sessions of wifi browsing, and brightness set to 25%, with stock 1750 mAh battery) :

well the thing is that I saw people around here getting similar with data active. And I get that with no data connection. Or maybe I don't recall correctly :silly:

Both. I can usually consistently get around 12-15 hours overall on Wi-Fi and around 5 hours and 15 minutes of screen on. Thats as far as i can push it with normal use like browsing on tapatalk. Browsing the webs... Google+ and Youtube normal "smartphone" activities. I dont have anything syncing i refresh things my self... and am normally on my laptop anyways. But on my Crappy Sprint 3G i only get around 2 or 3 hours with the same overall time.

Could be that the CDMA ones have battery problems (since you mentioned 4G).

I get these weird sudden drops of battery. Below 25 % it goes down to 0% in about 40 minutes of screen on time. When the battery is above 25%, it goes down by about 20% in one hour of screen on time. So the difference is big Anyone else is having faster drain below 25% or is my battery broken?

Why did you quote the entire OP in your post? It's pretty obvious who you were replying to, it was the second post!!!!

Reading over this thread, all the individual posts only present one combined set of what I consider the bare minimum info to have a battery life report be intelligible:
-Capacity of the battery (this is the one it seems like nobody ever mentions, props to ÜBER™)
-Total time
-Screen on time
Without all three of those as the foundation I don't think that any of the other info people like to quote can actually be understood. Qualifiers like "mostly on wifi/all on 4g/[screenshot of stats]" are still important for further context, but they stand on those three to mean anything.
A sample of my reactions to posts missing one of these, and what I've come to just assume about them:
-Oh your phone lasted twice as long as mine? Great, you've probably got a battery that's double the capacity.
-Your screen on time is incredible? Oh but you have the exact same screen on:total time ratio as everyone else, just dragged to one extreme.
-You think something's wrong with your phone because you don't get as good battery life as everyone you see posting on XDA? Oh but it turns out that you unplug it and don't put it down until it's dead.
Pissing contests are still contests, gotta follow the rules people!

When you said this was with no data active, does that mean data is actually disabled, or just that you're not using it?
Just looking at your screenshots and comparing the slope of different parts of the graph, nothing looks too out of the ordinary. Your one stretch of inactivity is nice and level. Your periods of sustained use all seem to drop at a comparable rate.
If you're concerned that the battery is erratic, try putting it in airplane mode (not just disabled data) and seeing if it doesn't just flatlane. This should reduce pretty much any interference in your data (unless you can see that a rogue app keeps the phone awake the entire time, but that'd be obvious if it happened). Obviously the catch being that it would probably take weeks to get a full picture, so try just draining it down to a low state and flipping it into airplane mode before you go to sleep. Flatline for the night= put the issue to rest. Highly variable graph=get a new battery and put the issue to rest.
But from what you've written, nothing looks out of the ordinary about your data to me. Sounds like you're not actually firm in the belief that anything is very different, just concerned that you broke something and looking too hard to find things that aren't there.

That sounds like a good plan. Thank you. Also, I should add that i use the stock 1750 mAh battery. Added that info to the OP also.
What I meant by no data active is that data connection is disabled in the settings

Idle battery drain

I've been noticing my battery drain about 3% on idle after taking it off charge. It's really annoying as 3% to me is too much. I've attached the battery screens to this post below.

Device Idle is responsible for 1.32% drainage from your battery. No problem here. If I'm misunderstanding, please rephrase.

Actually This is what I was referring to, when using the phone the battery drains nice and slow. better than I would expect to drain during screen on time. But when I take it off charger at 6 am and leave it in place and come back at 11 or 12 am I lose about 10% which shouldn't be normal imo. See below:

looks to me that ur messaging app is going crazy...everything else looks normal.

what can I do to fix this? Its annoying. And no this shouldn't be normal, I like everything about the stock rom and wouldn't like to root just for the hell of it. But this actually has me thinking, (still leaning towards no as I still get thru the day) but would like to get if fixed non the less.

I noticed the same thing. When i unplug it in the morning it drains faster. But when im waiting for the fully charged notification to pop up then unplug it lasts longer. Its strange, maybe has something to do with charger. Do they have "safe mode" after fully charged to prevent overcharging or something?

I always wait for the battery fully charged unplug charger notification to pop up before unplugging. So that doesn't seem to be the problem.

Faster drain is normal from 100% to 90%. It was explained to me that when you leave the phone on the charger overnight it charges to 100% and then allows it to drain some, then starts recharging again. You may really be at 95% when you pull it off the charger despite what the phone is showing.

First, get Better Battery Stats. It can help you figure out whether something is eating your battery abnormally.
Play store link
Also, I highly recommend GSam Battery Monitor It might be a little easier to understand than BBS, but I like and use both.
Finally, read this: Your battery gauge is lying to you!

BBS should be the best app to find out which process is your problem.

This phone gets hot randomly, guess it was just humid in your car. I feel like all this battery talk is useless android has never been good with battery life. This phone is huge and powerful so battery drain is going to happen. Also depends how long you had battery, how much you over charge battery. I read in several places that after 3 to 5 months of use batteries tend to drain faster.
Your best bet if it's such a big issue is getting another battery with a separate charger. Honestly in this day and age these smartphones should come with an extra battery lol

My battery and phone are both less than a month old, as for humidity that doesn't drain a battery from 50-0% on idle in a few hours. Also I've posted new screenies, messaging used ~20% without being used and stats showing 0s awake. maps did something similar despite disabling all location services and unticking all boxes in the gps submenu. My issue isn't bad battery life, its idle battery life. I shouldn't lose 2% per hour or more when I unplug and go back to sleep.

Battery percentage setting issues

Hi again,
Just about to give up on this tablet when I noticed that it seems to be the battery percentage setting that is causing my charging and discharging issues.
With the setting turned on and the percentage visible, the battery seems to discharge and charge oddly, and also the percentage shown does not reflect the amount shown on the battery icon, or at least it rarely does, but it varies.
With the percentage setting off, the discharge seems much slower and predictable.
If you have a p600, could you possibly try this for me with and without and see if it matches with my findings?
Thanks.

I'm having very odd battery issues myself. I'll give this a try and see if it improves for me.

Thanks for the reply. I'm not using any battery app, just the one that comes with the stock tablet.
I think I did encounter the same thing as you, and also unplugging at 100%, then taking it upstairs and looking and it was 96% or so, and then after a restart, it was 100% again. Very odd, but it doesn't do it for me unless the percentage setting is enabled.

No i suspect my device might have some deeper issue. I can drain the battery from 100% to 0 in an hour of playing games but if i turn off the note and turn it back on, it'll be back at 60% or whatever it's actual battery level is. I can rinse and repeat and slowly get it down to 0. Either way the battery drains much quicker than it should. It could probably only last 6 hours of screen on time with very light usage. I might need to get motherboard or battery replaced.
I am still hoping that its a software glitch and something like this could fix it.

I've had it since it was released in october or november and the battery life used to be good and last 10+ hours and probably 5-6 hours while playing games. Not sure what happened in between. It has taken a few very light drops with no visible damage and i did break (bend) a charge with it in the tablet but the charging port seems normal and still works fine.

Just checked with battery % off for 30 mins and battery dropped 4% which is normal.

Is your unit still rooted????? If so have you tried removing root and installing the most current factory rom.
Have you seen this post "Longer Battery Life (or How You're Being Robbed!)"
It may help some that are having issue with battery drainage but after seeing your post #36 in the BATTERY posting .... I'm leaning towards a cracked or damaged board from the few drops you talked about.

I've tried unrooting and odined back to a factory rom, also cleared my SD cards, nothing helped so i'm back to being rooted for now. I've done a lot of the tweaks to improve battery life but whenever I play games, it just drains like crazy even with minimum brightness. The drops were very very minor, like from 1 foot onto carpet and with a case so I doubt that it was the cause but I guess theres always a chance.
I'm still wondering if I should just live with terrible battery life and stay tethered to a charger or risk sending it back to samsung and having them find out it was rooted and overcharging me for repair. And I love the device so much, I don't know if I'd want to give it up for a week or two.

Thanks :good:
So, I wonder which is correct, the icon or the percentage? If the percentage is right, my tablet is faulty. If the icon is right, it would seem to be ok.
And all these reviews and people that get 10-12 hours, I guess they went by the icon?

The percentage gives a more accurate time I guess.
But people and myself use the "Screen on time" as the usage data.

Was doing ok last night and then came here and the battery took a dive. Went and grabbed adblock for firefox and ghostery and ghostery was reporting 65 trackers on this site. Also the malware popups were becoming ridiculous and they only happened here. Going to do a factory reset and not come come here tonight, see if that helps anything.
I did do a bit of a search regarding the malware here, and it was being reported as early as last june it seems.

another battery life issue

I'm sure this question has been asked before. But I'm coming from an iPhone so Neff help with this.
As soon as I start using the phone in the morning when it's connected to WiFi. Within a second of using it or 2 minutes if we're being realistic. The phone loses 2%. Is this normal ? Coming from an iPhone where 100% would last at least 20-30 mjnutes. I can't seem to find anything draining my phone either !

I think a longer observation period (a full day / through the night) will give a better idea of how your battery performs. Use the default power settings or other batter monitoring application like GSam Battery Monitor and compare it against other users here.

I'm sure this question has been asked before. But I'm coming from an iPhone so Neff help with this.
As soon as I start using the phone in the morning when it's connected to WiFi. Within a second of using it or 2 minutes if we're being realistic. The phone loses 2%. Is this normal ? Coming from an iPhone where 100% would last at least 20-30 mjnutes. I can't seem to find anything draining my phone either !

Had about 3-4 days worth this end will keep an update here. So far not bad been intense usage for about 2-3 hours lost about 25 percent. Could be worse

If did that across the whole day yesterday let me show you the result. I usually charge when the phone gets to around 35-40%

Well that's 3.5 hours of screen on time and you're at 45%. That doesn't look bad to me.

Okay just making sure I'm getting the full potential of the phone Lolz reviews kept saying 6 hours but that's assuming they let it get to zero

Any update?

Got nearly 20 hours off charge with moderate usage throughout the day with a mixture of WiFi and 4G. Turning power saver at 50. Phone had 33 per cent left by end of day.

Urban myths and old wives tales. Cycling the battery doesn't "improve" battery life on a Li ion battery. What you are possibly doing is making the battery meter more accurate (placement of the "high" and "low" flags that correlate voltage with "full" and "empty"). But its just a means of measurement, and this doesn't affect the battery life itself. Meaning, it doesn't "improve" battery life any more than messing with the fuel gauge in your car would increase or decrease the amount of gas in the tank.

This doesn't mean anything. The battery % is just an estimation based on battery voltage remaining versus how the phone "thinks" you are going to use it. Comparing 98% on Android versus 100% on iOS is apples to oranges. There is no standard for this, or reason to believe they are in anyway comparable.
As previously noted, 3.5 hours screen-on time with 55% drain (45% remaining) is very normal, even good. A lot of things affect battery life, not least of which is how you use your phone, and cell reception in your area. You will see a wide array of variance in the battery life people get. And since yours seems actually pretty good, I wouldn't worry about it.

Thanks [emoji3] it was actually &37 percent but that's still pretty good with the battery save g options available I should be able to exceed a full day in the event of an unplanned night out !

To be fair, I feel like Apple designs their phone where their first 20% will take forever to drop but as soon as it passed that point it falls to 0. And yes I've seen it shut down at 10, turned it back on it's at 2. Where as this phone's last 15% seems to take forever to drop.

id say thats pretty good life outta the battery. the more you use it the more its gonna drain. and those getting like 6 hours of screen on time are strictly on wifi at an office or something. if your out roaming with LTE and the such your probably not going to get 6 hours...

Intense usage on 4g with lots of camera usage and uploads music and a few phone calls. So far so good! Had more than enough when I got home to leave without changing I case I needed it

I feel the M8, and my past Android phones take a disproportionate amount of time to drop the first few % as well. Maybe not as much as what you are mentioning for the iPhone (couldn't personally comment). May have to do with the saturation charge that occurs when the battery nears full (in fact, you should actually leave your phone on charge for some time after it says full).
Also, the battery meter on any phone is far from accurate. It often can't really be trusted with be within 5 or even 10%. So that would explain why you saw it "jump" down 8%.

Yeah my point was that all these phones' measure battery differently and not exactly accurate so you shouldn't compare Apple to oranges. Oh and the jump in percentages was referring to the iPhones. If anything Android tends to jump up when turned back on lol.

Battery goes from 45% to a warning to the phone shutting down in less than a minute. Really getting frustrating.

Most likely a bad battery. Are you using the OEM one or a third party one?

OEM
I don't think it's the battery.. It really only occurs when I have location services enabled.

I had a similar issue. Replaced battery with another OEM Battery that came with an external OEM charger and hasn't happened since.

I was having the exact issue, it started at 15% then 20% till finally it was happening at 45%. I bought a new battery on Amazon and put it in last night. Take a look at today's results and still going as I type this.

You have a bad battery. There are no software issues in our firmware that would cause such an issue, so it isn't something like that.

I have the exact same problem, my battery is OEM. It will be at 45% then shut down completely. When I put in the charger it's at 0%. I'm now living near an outlet daily. Guess I should hit up Amazon too! ?

You need to calibrate your battery. Google how to do so

I just ordered a new battery.. I'm tired of it dying on me with 35 to 45% battery left.

My original battery started dying like that at about 25-30%. I was about a week from the end of my warranty and so AT&T tested my battery then sent me a replacement. Haven't had any battery issues since.

Battery calibration is a placebo. It does NOTHING. On old Android phones, it did, but not with modern hardware.

Worked for me when my battery was doing this at 25%. Calibrated 3 times and never have had the issue happen again.

So here's the thing. I've been declaring it a placebo based on a bunch of research I've done. Well, after looking through my research again very closely just now, I realized that the term "battery calibration" is used to represent two different things in the Android community. (1) Calibration done by deleting the batterystats.bin file in System/data, which usually requires root and can be done via calibration apps or manually, and (2) Calibration done by simply charging your phone to 100%, waiting a while before removing it from the charger in order to ensure that it's truly at 100%, then draining the battery down until the phone dies.
#1 is truly a placebo. It does absolutely nothing. When someone mentions battery calibration, they usually refer to method #1 and will ask about calibration apps or something like that.
Method #2 on the other hand has not been debunked according to my research and theoretically makes sense. From my understanding, newer Android phones have a chip that can sense the battery level and capacity of the battery placed inside it. So, if you put in a larger capacity battery, the battery level displayed on the phone should adapt accordingly. However, it depends on the type of batteries. I forget exactly what they're called, but some batteries, like the Zerolemon 10,000 mAh battery, are just 3 stock-sized batteries linked together, so the chip gets confused because it reads one "stack" at a time. This leads to symptoms like the battery levwl dropping steadily until like 30%, but then staying at 30% for a few hours before dropping to 29%. Or the levels dropping but then suddenly rising without being on the charger.
With other extended batteries that use a single "stack" instead, like the Hyperion extended battery, the chips read the battery level just fine.
So in conclusion, whether or not it's a placebo actually depends on which method of calibration being referred to. When you simply mentioned that it needed to be calibrated, my first assumption is method #1 since it's more commonly used in the Android rooting community. But if you're referring to method #2, it may or may not help as it turns out.

Yes I was referring to method #2. I guess I could have put a bit more detail into my post. But I also came across the same information you did when I was researching this problem that my phone was having when going from 25% to 0%. I was never able to try method #1 on this phone because there is no permanent root so I've never bothered. I can across method #2 and that's what I did. I also got the same info as you when I was looking into purchasing a zerolemmon 10,000 may battery but decided against it because of the way this phone reads the battery. Also OP: try not to use method #2 often as the battery reaching minimum capacity really hurts it. The battery's optimal performance is between 20-80 percent.

BTW with this particular phone the Note 4 in general not just this variant it's the chip in the phone that reads the battery level that gives off the incorrect percentage left not the (zerolemmon) battery itself. The note 3 I believe was able to show correct percentage. Its something with the chip in this phone
