My stock unrooted 16gb n7 received the 4.2 update this morning, all has been fine until this evening when it needed charge.
It often gets plugged into a htc phone charger, which has worked fine since i bought the tab a few months ago until today, its a 1amp charger so it takes ages to charge, but thats fine as it is plugged in until the morning normally.
So i plugin as normal, and come back after setting up google play music on my desktop pc, and i see the unit rebooting showing the glowing X. The screen goes blank and is unresponsive, eventually the google logo appears and it boots normally (its still plugged in btw), after unlocking the screen goes mental after maybe 5 seconds with random noise on it, then goes black.
So i unplug and use the genuine asus charger and cable, it does the same twice over, reboot, freeze, long wait then reboot.
I have now left it on charge using the asus charger and it seems to be ok now
Have google changed some charging requirements? Anyone else seen this?

Not sure, but my nexus 7 on Android 4.2 charges like 35% slower than did with 4.1.2..... what the hell did they do??
Funny you mention that, i might agree with you there
The N7 seems fine today, i did make a couple of videos of it misbehaving last night, watching back my circle battery widget app jumps from 16% to 0% battery just before it goes blank, indicating it might have simply run flat but thought it still had 16% battery?
Wonder if they have changed the battery meter scaling?
I think i will run it flat and check it shuts down properly like it used to

Hi dexterslab,
On a side note when you update to 4.2 were you already rooted and did you have superSU version0.98 installed? I have been reading other posts in this forum that folks have been rooted, superSU installed and the update has completely crashed their N7. ANy info would be greatly appreciated.
Thanks,
JBIRD
Its still as stock, locked and unrooted

I've noticed slower charging since the 4.2 update too - did a quick Google search and landed here. Using the same genuine Asus charger and generic cable that I did before the update, and I would agree with the roughly 35% slower estimate.

Thanks, did you do a factory reset prior to updating?
No, update received ota so just installed it

Are you using the new Daydream feature (you can find it in the display settings). If yes this may be the cause of slower charging, because it doesn't turn of the display.
Daydream is off.
Tbh, now it seems to have settled down i think maybe charging time is pretty much the same as it was. The whole debacle seems to be a complete non-event in hindsight!

No Daydream for me.
Mine is stock and unrooted. After the update I'm having the same charging issues. Incredibly slower charging. It's been plugged in for 6 hours now and it's at 80%. I did play a bit of pandora for about 30minutes but it was still plugged in. Other than that I haven't touched it other than to check the level. I turned daydream. Let's see if that help though I doubt it.
i think when you install the 4.2 update it does a battery stat wipe. this could produce the battery jumping from 16%-0% i reset the battery stats on my gt-i9003 the other day charged, its went from 100% - 40% instantly after about 2 charge cycles it should go back to normal.
it would also explain the battery seeming to take longer to charge, its just the voltage counter resetting itself. it might even in some cases charge faster....then run out quicker....
charge- discharge about 3 times and it should go back to norm.:good:

Agreed, phones seem to be more universally compatible when it comes to charges.
Charge a tab with the wrong charger n you'll make up with a melted Nexus 7
i think its a part of certain regulations now that mobile phones needs to have an internal capacitor/transformer to make sure of this problem, as people usually run out of charge on the go and use other chargers as long as the connector fits and it begins charging, most of us including me are probably guilty of plugging a charger in, seeing its charging and thinking *yay it works fine* walking away and not really understanding what slow-fast damage can be caused to the device/battery.
for tabs 30% i would say dont have this feature:good: especially the Chinese ones. ? <no racial offence intended> you guys know what im on about.
My Nexus 7 worked great before upgrading to 4.2. Now it can't charge while I'm using it... The battery just goes up and down as I'm surfing the web, if I load a lot of pages, it goes down, if I read a lot, it goes up... But if I try to watch a floating video while surfing the web, it just goes down... There is definitely a problem! Here is a screenshot... I'm using the original charger and cable...

Wiping battery stats does absolutely nothing that affects reported battery charge level. That wives' tale was long ago debunked by a member of Google's Android team. The one and only thing you are wiping is a list of apps that have operated on battery since unplugging after the last complete charge. This in no way, shape, or form affects reported charge or has any effect on battery life whatsoever.

LIKE I AM SAYING MY FRIEND,
actually the battery stats ARE WHAT THE GOOGLE DEV SAID is what gives you accurate readings it doesn't increase your battery life . i never said that it will, so please don't police me,.
heres the comment
This file [batterystats.bin] is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings. That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
when you flash a new firmware, the system must calibrate as there are no previous readings from the bstat file right?.,these are the readings that help the system produce the reported battery charge. its what it does to give you those readings, i was guiding the above member to wait and run a few cycles for readings to be more accurate i never said his battery was dead.
kinda why pretty much EVERYONE mentions after flashing a new firmware on most device they have a few days of battery "up-n-downs"= counter reset/data collection/last battstat file wiped.
cheers:good:

Read her entire dissertation, and you will see that it does not pertain to reported charge level. She explicitly states that batterystats.bin has no bearing on reported charge level. Interesting that you left out the portions of her post immediately prior to, and immediately following, the part of her post that you quoted... you know, the ones where she states, and then restates, that nothing in batterystats.bin affects the reported charge level? Also, the reason the battery seems more stable a few days after flashing new firmware is the kernel itself settling, not the OS.

I`ve had the phone for 3 days now and before upgradin from the Iphone 6 ( my first and last iphone) i was really anxious about the many issues listed in the forums especially the touchscreen problem. When i initially got it i started testing everything and I`m glad to say that everything worked fine (sooo relieved) but when i charged it for the first time it charged very slowly, about 3 hours for a full charge, and it got really hot when using lightly the 3rd day a did a factory reset and immediately noticed the the battery charged way faster about 1% per minute ( i dont know how it compares to you other guys) and the phone didnt get nearly as hot. From all this i belive that LG did e very good job hardware wise but i think like many other conapnies fell a little short on the software department and hopefully it will be fixed in the updates to come.

Mine will start getting hot and eating battery once in a while, but a reboot always fixes that. 1% charge per minute is about what I see on the stock LG charger.

Glad to know its not only me. Have you used a QC with the phone? I ordered a Tronsmart 2.0 QC off ebay hopefully it will work faster without any issues.
I bought the Tronsmart QC 2.0 and its awesome. I go from 48% to close to 100% in the 45min car ride home. I do not notice any heat that is worrying. It does get warm when charging but normal.
My G4 was raging out of the box. Super hot. Brightness was being throttled back between 100, 90, and 80 pretty frequently and it went from 60% to dead in like 15minutes. After I wiped and setup as new, it has been running as one would expect.

Glad to hear that ☺. I actually purchased the wall charger but i guess the performance will be similiar. The one thing i noticed today was the battery life, it seems it is not that great during very light usage but that may be due to the fact that these couple of days the reception has been awful because the carrier im using (Vodafone) is switching to 4G for the first time in my country and ,a little out of topic i know, the download speeds have shocked me, my home connection max download speed is about 400-500kbps and today i witnessed 15-20mbps.
Battery does drain faster in low signal areas. I found that a slow charge at night yeilds longer charges throughout the day. I use fast charge in the car so I can use GPS and still get a charge. But at home and office I use Qi Wireless Charging. I use fast charging at home but only when I am doing heavy useage. I slow charge while I sleep.

How much of a charge do you actually gain in the car with the fast charger while using nav and music with screen on?
Is any of you guys using a micro sd? Im using a Samusng 64Gb class 10 and im experiencing a lot of battery drain even when the phone is on idle and i was thinking if the card has anything to do with it.
I'm using SanDisk class 10 and there's no noticeable difference in my end

It could be the phone is performing media scanning which keeps the phone awake. This should be completed in a day or two.
If you still experience battery drain after couple of days. I'd suggest performing a full format of the micro SD card on a computer. Incase there are bad sectors on the SD card that the phone is stuck on try to read them.

The funny thing is that the the two buying factors for me were the removable back and the micro SD slot, and the only issue I have may or may not be with the micro SD and a slightly loose hinge on the left side of the battery cover but I have experienced that with every phone I had including the g2 and the iPhone 6 without a removable back that had this issue.
Hey,
This is my first LG phone. I'm a bit disappointed, but the camera makes up for everything (mostly).
First of all, the device I'm using right now is the third one within a week. I got it from Vodafone, and the first two had the same issue. When the screen was on, and showing bright things, the front speaker would give out a high pitched whistle sound. You could only hear it initially if you held it to your ear. However in recorded videos it was clear and loud enough to be very very annoying. This third unit is ok it seems, but my advice to everyone is to try the G4 before leaving the shop. It might just be a bad batch that was made for Vodafone, a similar thing happened to me with my HTC One X, that had screen issues, and there too I had to go through several devices.
I did notice lag, Nova Launcher helps, but I'm really looking to root the thing and putting CM or some AOSP rom on it. My S5 seems way snappier with BlissPop on it. The only problem with that is I loose the camera app, the thing I bought it for in the first place.
The battery is ok, but I expect more. I haven't had heat issues. The GPS draines the battery though really bad. If you don't use a charger whilst navigating, you'll go flat within an hour,which is not stellar at all. If you use a normal 2.1A charger, you can keep it on level, or might even add a few %.
The camera is awesome, and the leather back too. Cool that at Vodafone you get the leather and a plastic back in the box.

Thankfully I didn't have any hardware issues, I have the Hong Kong version because there's where most of retailers get the phones in my country, I think there's a lot room for improvement software wise and I'm hoping coming updates especially android M, will refine this device even more. I really hoped my I would get the plastic back cover in the box and I'm really jealous of those who did ??
Im starting to notice two more things with the G4, the battery cover (leather) is making a creacking noise when i press it on some areas, and the other one is the with the vibration motor that makes a little bit of noise compared to other phones ive had, has any of you guys experienced this?

It's up to you, but as you have seen its much recommended if you have any issues.
Hello guys!.It's my first time here. So, I have some questions regarding this problem
I bought my S7E around july, and it had amazing battery life, It lasted around 30hours++ but I drained the battery by playing games so I can charge my phone before 5pm(my office hours) to avoid over charging when I go to bed. I even used the best perfomance that time, gps on, gestures on, etc.But still at least it lasted for 27hours.Now, it only lasts for about 12 hours something. Ive never overcharged it. The moment I saw the green led, i plugged off the charger.
Can anyone fix this? well please don't tell me to turn off all the features, I had them on and still I got to use 27hours. I dont know when I did the update, maybe os 6.0.1 is draining the battery?or any suggestion?
Thank you
Go to Settings>Battery and view the usage to see what app is using it much battery.
You can NOT overcharge the battery of your S7 Edge. I've always kept my phones on the charger over night and never had problems. I'm doing that since the HTC Magic (T-Mobile G1). It has overcharge protection. It is NOT good to drain a Lithium-Ion battery down to a few %. A Lithium-Ion battery operates the best when charged >40% and at average room temperature. For more info, visit batteryuniversity.com.

Nope. I never drain my battery.I keep my battery until 20% then charge it directly. I know how to take care of Lion battery. Ive heard about the overcharging protection feature but i'm not sure whether it works.we never know whether that program runs on background or not since we cant track it.

Well, then don't charge overnight. You're problem is most likely software related anyway unless your battery is very old and/or you overstressed the battery too often which can't be because the S7 Edge isn't that old and you "...know how to take care of Lion battery". I think you meant Li-Ion but w/e. A defective battery is possible but very unlikely. BTW overcharge protection is not a program. It's a physical thing soldered onto the battery/charger PCB. Hardware. There's one built into the battery and one inside the charger and of course we can track it. You can't because you probably don't have the equipment + knowledge to test it. If you're so concerned, you should really read about it. After all, you're dealing with a highly reactive metal.

Well that's why i charge my phone at my office:crying:
i wonder if the OS is the problem. I've heard about drivers not compatible on s7 using 6.0.1 so the background data keeps working such as gear vr service. It wasnt there before. and OM Customize. So, if i overstressed my battery, it will damage my battery? I did that before to charge my phone between morning to evening.

You're hearing really weird things buddy The S7 Edge has always been running Android 6.x.x. It never ran any other Android version. The drivers are fully compatible. In fact, the drivers on a Samsung are as compatible as drivers can get, since SoC, Camera Sensor and many other parts of the phone are coming from the same manufacturer; Samsung.
My guess, and I can only guess since we'd have to see your battery stats for more detailed explanations, is that you either ran into the Android System-, or Google Play Services battery drain bug that occurs after an OTA update. These problems date back all the way back to the Galaxy S2.
I'd recommend you first flash a stock ROM using the "HOME_CSC" file. This will NOT wipe anything from your phone. Only the core system and stuff will be reinstalled. If you still have this problem, try flashing a stock firmware using the regular "CSC" file. Always make a backup first. The regular CSC file will WIPE EVERYTHING from your phone, including internal storage but it won't touch you MicroSD. Now you start with a freshly installed Android and see if it solved your problem.

Hello mate,I am sorry for my late reply since I gave up. I am trying to solve this again.
Well, can you tell me where can i get the stock firmware? I am from Indonesia(well I think some parts of the continents have different firmware).I wanted to flash it tho but I am afraid I got some "hacked" firmware.
well,the battery usage looks normal to me.
google play services around 5-15%
android OS 15-20%
android system 15-20%
but still,it drains too much>,<
Let me try to upload a pict of it.
Additional information : Slept 8 hours while listening to music and it drained from 55% to 2%.I mean this is really insane.That's why I am taking serious action now. The first time I bought it with the same settings and apps + I turned on always on display and night clock while listening to the music for 8 hours of sleeping,it only drains 10-20%.
I took this ss because I got 30hours on time : link
these are the drained ones.15Nov and 9 Dec
15Nov
9Dec
Thank you mate
First out of all. How much SOT (Screen On Time) do You get?
To check that go to battery usage at the end of the day or when You have 20% and in battery usage tap on screen and take a screenshot.
Second.
Certain firmware updates decrease battery life a little.
And third.
You can disable apps that are draining Your battery if You don't need them.
Also for a really good battery info what uses Your battery etc You can download GSAM battery monitor from play store.

well from the time being, i think my network operator is draining my battery.I tried to turn off my mobile network last night and used wifi instead.I lost 1% for 8 hours.Well, I changed my network operator around october and since then I felt the battery drain. I already sent report to the provider hope they solve it.
But I wonder, my network operator has good 4g coverage here, why does it drain too much? My old operator had only 3g coverage.Is there any way for me to track down my operator whether they are using too much battery to search network coverage maybe?
Newest firmware always decrease battery life a little
Hello and Happy New Year to all,
*
I came across an issue with my Note's (N910C) battery today and I would like your opinion on it.
*
A quick background:
*
The phone has never been rooted.
9-10 months ago I downloaded an official firmware (6.0.1) which I flashed via Odin and it began to drain the battery very fast, killing the phone in less than a day.
I got a new battery, but the problem was still there.
Eventually I tried another firmware which worked nicely and consumption returned to normal levels. Since then, I had no problems whatsoever.
Yesterday night I got a notification to update. I had already done another two in the past - if I'm not mistaken - , without noticeable difference.
I did the update overnight and I removed the charging cable in the morning. It seemed that it was a little warmer than usual, but I did not pay attention.
The battery percentage was reducing at the rate of 1% per minute and it died within 2 hours.
I checked battery info, nothing abnormal.
I have two questions:
*
1. Does anyone have similar experience with this model (or other)?
2. If I reinstall the previous firmware, normally the problem should be fixed, right? I mean it started after an official update which AFAIK affects native apps only.
*
Thank you in advance
I have noticed on my Note 4, after upgrading to marshmallow, the battery drained like crazy too. It would drain 10-20% when I use it for 20 mins or so. The battery that I'm using is a 'new' one that I bought just about a year ago although the problem still occurred when it was fairly new.
I'm speculating that there might be some sort of battery or software issue with marshmallow as the original battery that came with the phone also had the same issue. It would drain fairly quickly until one day it just stopped working and would boot loop until I plugged it in to the charger.
Ever since marshmallow, I have never seen my battery get to 15% before switching off completely. Sometimes even 45% lol.

I had a faulty N910F and got another (used) one and it's had occasional forced closes at between 15-20%. This worries me that it might go the way of the old one where it developed the issues with it freezing and the frequent reboots....does yours exhibit any other issues?

Yes. Unfortunately. Currently, it would just die halfway even when I'm at 50%? That's the highest that I've noticed. So I had to charge it up for a bit maybe to 60% and it would be fine before dying around the 20+ - 40% mark. Previously, the original battery that came with the phone had this weird issue where the battery won't hold any charge even when it's fully charged. Like it will go to a bootloop when I've unplugged it even though it's at 100%. When I bought the new, current battery I noticed that it would still die off at 15-20% and the original battery became bloated a few months later.
Are you using any custom roms? The bootloops and freezing could be related to using some custom roms. I changed from a N7 port to a deodexed stock rom and the frequency of the freezing and reboots just plummeted. Reboots only happening when the battery is close to dying.

Ah right, so you had only the reboots, nothing else? That's fair enough.
No, it's nothing at all to do with the ROM. I'm stock but LOTS of people have had the same issue. As it stands, the only way to fix it is to get a new mobo :crying:

Well besides the usual overheating that's related to our snapdragon CPU, nothing much but mostly battery issues.
Although there is thread that I'm following that promises to fix the 15-20% issue. Checking their method to see if it works or not

hey can you give me the link of that firmware that improved your battery life
I had a similar problem with fast battery drain - did a factory reset and it's back to normal. Make sure you're using a battery from a reputable source like RavPower (don't think there are any genuine Samsung ones left and Anker stopped making them).

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.
I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh my power app tells me I have 2520 too but I really dont....heh
---------- Post added at 03:12 PM ---------- Previous post was at 02:46 PM ----------
Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol
My battery is from October 2015. It's the original one that came with the phone
Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?
Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).
Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle
I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

Ive just unplugged it 50 minutes ago and I have 10 percent left with only 10 minutes screen off... There is something wrong and I don't think the two batteries (old and new) are in bad state in the same way... There may be something else..
Have you tried to install the stock firmware through odin? PS: Read the instruction before trying it!!!

Make nandroid backup with TWRP and flash official firmware. That's just not normal for any kind of battery (good or bad)

Right now I have DreamUX V2 A7 (2017). I flashed one week ago hoping to remove this strange battery behavior. But it remains. Do you think reflashing stock firmware will fix it? I'll check instructions before going ahead. Thanks to both!

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

OK I'll go ahead with this. Good guide to reflash stock rom?
I'll do several factory resets to see if it helps, but I start to think that it's black magic
Thanks
Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help
