[Q] Battery charges abnormally fast - EVO 4G Q&A, Help & Troubleshooting

Hi, phone seems to be charging much faster than im used to. i mean like from 4% to 70% in under 2 hours.
Wondering if this is an issue with my setup (in sig) or some other factor...or if its not really an issue.
Cant comment on the battery life after a charge like this as i have not used it yet. I have however had poor battery life the last 2 days, but i think that was because of the pri/nv 1.90 issue, and have since downgraded to 1.7x.
tomorrow i hope to see the expected battery life, but the charge time is concerning me.
Anyway like an app to test the battery readout for accuracy? currently using mini info along with the notification area battery indicator.
Thanks

Was this with the stock charger? or? I know when I use the usb charger that came with my Nook with my EVO it charges in about 1/3 the time. I've never really compared how "solid" the charge was but I've always done this when traveling and don't remember my EVO draining abnormally fast.

Until you can conclude that your battery life has suffered then this sounds like a blessing. What I would suggest doing is letting the battery drain out completely before your next charge. Batteries need that sometimes.

I always use the stock Evo usb cable with either my powered USB hub or the stock wall charger. Its been my experience that the USB charging is a little slower then wall charging, but last night it charged extremely fast. I went from 4% to 100% in a little under 2 hours.
Could have just been paranoid because my battery life yesterday was abnormally low, a result of having pri/nv 1.90 i think (i downgraded to 1.7x last night).
I "calibrated" the battery last night by charging to 100%, unplug, replug, shutdown, unplug/replug etc. Did this a dozen or so times then cleared my battery stats.
Battery life will hopefully be normal today. Ill report back my findings.

[Q] Strange battery percentage drain in 10 minutes.....wtf

This morning after I got ready I took my phone off the charger (it had been charging all night and was at 100%) and walked upstairs. About 10 minutes later I turned on the phone and it was at 67% and going down. I had flashed a new rom yesterday and as quick as I could I did during the drain I did a NAND restore. Could this have been actual battery drain or is there something wrong with my phone/stats. Could my phone have stopped charging at 50% and then just said it was 100%? What should I do? Is there anyway to avoid this from happening again?! I cant go to work with a battery at 50%! lol
-.- Searching is your friend.
The Evo has never trickle charged properly. Trickle charging is when you hit 100% battery while charging and the phone will continue to keep the battery charging and maintain this 100%. So 100% > 99% > 100%.
The problem is the Evo doesn't do this. Once it hits 100%, it switches to battery. It will run off the battery till it hits about 90% and then charge again. Some even say it will NEVER charge again after it hits 100%. So when you unplug it in the morning, you end up dropping extremely fast from 100% to 90%.
There are kernels in the development section that fix this issue but there are people who say it will break your phone or burn your battery out faster over time. When trickle charging, your phone will get hot as its constantly draining and charging. That can lead to a burned out battery as time goes on or a damaged phone. I personally have three batteries. I still tried to use this and noticed a drastic improvement but my phone was also pretty warm when I picked it up in the morning. Its up to you.
Also you might want to see if you have your 4G radio on. That is probably the only thing I can think of that would drain it that fast. Either that or your GPS is on and theres an app running thats using the GPS receiver.
i'd say a 30% drain in 10 minutes is unnatural. it wouldnt be myns rls4 that you flashed, would it? this is experianced by some as a "first day side effect". just fully drain and fully charge the battery a few times and you will be fine.
It could be that it just needs a couple drains and I don't want to quickly point the finger at an app that you are using. A lot of times if I actually charge my phone it will be on 92% when I wake up. 67% is a stretch unless that was 10 minutes of a game or YouTube..but still. Drain the battery a few times and see what happens.
i was thinking maybe its some kind of battery stats problem? Could that have caused it?

[Q] Not sure if I have found a battery drain bug or what

Something I've discovered recently, and I am not sure I can explain it properly, but here goes...
I am running SRF 1.1.1, I don't believe this is the cause of the problem, but probably something that should be stated.
So running SRF1.1.1, I usually get wonderful battery life. I typically use an external charger and swap out batteries when they get to around 10-15%. This has worked well for me.. For the past few days I got lazy, and just plugged my phone in and left it on my desk to charge, no problem. When the battery is fully charged and I unplug it from the charger, I noticed it was rapidly draining.... I am aware that often when charging via the phone the battery immediately drops to 96% when removed from the charger. So this is normal, but I've noticed that after unplugging from the charger I lose about 10% per hour, when normally it may be 1-2% depending on usage.
To remedy this problem, rebooting seems to fix this issue. I have also had success with the airplane mode toogle. I don't see any odd usages showing up in spare parts, but is there any other way I can test this theory?
Thanks!!
Edit: Wanted to add, that this only seems to happen when using the charger cable with the phone. Swapping batteries does not seem to produce this issue. It is only when the phone is removed from the charger.
I haven't calibrated by battery lately and thats exactly what mine does too, I would stick to the external charger because our phones charge excruciatingly slow unless off. Try calibrating by charging to full while on then turn it off and let it charge more and repeat that a couple times then boot into cwm go to advanced and clear batt stats
Is there an advantage to calibrating a battery if it is not being charged in the phone?
This is the TWS bug mixed with no battery calibration.

similar to what i have been experiencing. i enjoyed great battery life with srf 1.1.0. have a 3500mAh battery that i used to get about 48 hours out of, but now it is averaging around 25-30. i do not have anything but the stock battery to swap with, so i do put it on the charger nightly now. i was planning to recalibrate the battery tonight to see if that cleared things up.
what would be a way to fix the tws bug?
I have noticed this too. It seems to srf seems to not like my extended battery. I am lucky I get a day out of it. I some times will plug it into one of my work computers just to bring the charge up a little and it starts flashing red and discharging this is only on my extended battery not the 2 stock ones I have. I have even tried different kernals to see if that was issue it isn't.
Sent from my lean mean drunken machine useing XDA Premium and a 12 pack of Sam Lager
in looking at battery usage in >settings>about phone>battery use>cell standby i see usually 0-5% tws.
one thing i have noticed, though have not tested is that the screen appears brighter, even at the minimum setting than what i remember from srf 1.1.0

[Q] Why is my battery losing life, or not displaying correct percentage?

About a month ago, I flashed Gingerbread onto my Epic 4G. Did nothing else, been running the usual BatteryLife by CurveFish without any hiccups or fluctuating readings.
However, recently, I don't seem to be getting a full charge. Or, the battery likes to drain. Either that or BatteryLife is not giving proper readouts anymore. For example, I can plug my phone in and let it charge. Its LED will go blue and the widget shows 100%. But, now, sometimes I'll look at the phone again later (while it's still connected with the charging cord or not) and the widget will read something like 82%. And, just now the widget is now showing 78%.
My battery has been fully discharged and recharged many times before for proper calibration. I even ran a battery calibration app. Still, this problem happens. What exactly is going on? I have had the phone tethered to remain charged and never once had a problem with the battery. I do know when I flashed Gingerbread, my battery life has increased dramatically.
Charge till you get the fully charge notification
Then turn off
Then go into click work recovery
Go to advanced
Click reset battery stats or something like that
Put back on charger
This proly happens cause of overheats from the super crap **** gb leaks
Also discharging the battery doesn't help
Sent from my SPH-D700 using XDA Premium App
Then, why does everyone say to get the most out of your battery, you discharge it fully then charge it up to 100% about a couple times to maintain proper battery life and calibration?
There is an issue with some installations of the gb leaks where the battery stops charging at 100% even when it is still plugged in. I had this issue and could not remedy it. Went back to a solid ec05 base and my charging works fine again.

SGSII Battery Charge Speed (0% to 45% in 1 HOUR!)

Is it me or does our phones charge super fast?
I drained it to 0% (let the phone die by itself while watching youtube)
Then I plugged it in at 8:05AM this morning.
At 9:05AM it was at 45%.
Pretty impressive.
(Once charged to 100%, should I wipe the battery stats and drain down to 0% again? This is how you would calibrate it correct?)

If you are getting incorrect stats then yes, clear the battery stats. The best way to calibrate is to drain, refill & repeat. Along the way when the battery is 100%, turn it off and charge it till it says its full again. Do this a few times when it's unplugged and you will see better life.
Speaking of fast charge.
I had 17% left at around 12:30pm today. Plugged it in while I went to lunch. Now at 2:50pm, just got notified that it's fully charged. Not bad at all.
Also, I had drained my battery when I received my phone.
How is that even possible!!!!!!!!!
It takes me 3.5 hours to charge it full!!!!!
Damn!!
I have two lines and this is my second SGSII aside to the one I already have...
I got this phone just yesterday and last night was my first full drain....today was my first full charge.
Shouldn't I go into recovery and wipe the batt stats?

I noticed today that the output from the charger for the SGS2 is 5V 1A and all other usb chargers ive gotten recently have an output thats closer to an actual usb port (4.5-5V 500mA) so that might have something to do with it.
My test pool on this hypothesis is quite small though so id be curious if anyone else can corroborate
I notice my battery charges much faster on an official samsung charger. Anything below 1V charges super slow. I want to try a rapid 2V charger but worried it may ruin my battery.. but on the other hand, AFAIK, some samsung car chargers charge @ 2v. They're called "rapid chargers" This is one of those times where you think AH any generic charger would do. I used to be in that camp. But I really found that the Samsung chargers are quickest. Also, they seem less likely to damage the micro usb port due to repeated use due to the fact that the Samsung cables tend to be thin and light weight as opposed to thick and bulky like some eBay cables. The thick and bulky ones feel like they'll give you enough leverage/weight if grabbed the wrong way and tear your micro usb port right off.
In the end, I love the Samsung chargers.

Excessive battery drain immediately after unplugging from charger?

So I've noticed some weird battery behavior on my Pixel 2 XL and was wondering if anyone else has noticed this.
I normally like to ;et the battery drain down into 5% or so before plugging it in and letting it charge through to 100%. I started noticing that a full charge would take me nearly 2 hours fully charge. A couple of times last week, I had to step out and the phone was charged approximately 95%. I unplugged the charger and walked to my car (about 5-6 minutes to get to the car) and when I looked at my phone, charge had dropped to 88%. Over the next few days I noticed this kind of excessive drain immediately after unplugging the charger. Aside from this, I still achieve 24+ hrs of battery life on a single charge so I am not sure that it is a HUGE issue, but one I felt shouldn't be happening nonetheless. Last night the same happened - unplugged around 95% and i literally saw the battery indicator go to 93%, 91%, 88% and then stop at 87% in about a minute. I immediately called Google support, shared my screen, and after speaking with the person on the phone - i was told I should definitely RMA, which i did..so I have a replacement coming.
I don't use always on display or always listening and I am extremely good at clearing open apps before I put the screen to sleep. I have noticed this at home, on my wifi as i always need a charge later in the day when I'm home from work. Also, I use the OEM charging wire and brick.
Anyone else notice this ?
I have not noticed battery drain fast after unplugging at full charge level. I would say you probably should RMA the device. Also it is not good to let lithium-ion batteries go down to low levels a lot like that, it will degrade the battery faster. The less you let the battery go down to low levels, the more charge cycles you will have, which means long battery life over time.

I definitely did RMA, it was a painless process.
And I always thought that maximizing the charge of the phone (letting it get low, then charging up) would actually keep the battery healthier as it would reduce the # of times I charged it. Am i way off base with my logic for that?!
Going into my third week with my 2 XL and I haven't seen anything abnormal regarding battery drain.
I do practice the method of unplugging at 85% and plugging back in around 15% (per Accubattery's reco, and other reading done online)....
There's no proof that it helps as suggested, and while I realize that only allows me access to 70% of the battery's charge potential, I'm rarely, if ever, away from a plug for more than half a day.
This theory worked well in my 6P until it got the intermittent BLOD... My battery health was around 84% (via Accubattery) after 17 months of pretty heavy use.
Again, not sure it is solid fact or not, but you could always try it for a month and see if there is any noticeable difference in battery drain.
Thank you for that insight! I will absolutely do some research. You're battery health after 17 months is really impressive. I just switched from a Nexus 6p that was definitely showing signs of wear after 2 years of fairly standard use. I hadn't used accubattery, but I will download it on my new replacement and monitor results.
I will say though, that aside from that slight blip i noticed - the battery (andOS optimization i'm assuming) is amazing. I get through a day plus easily. So, anything I can do to keep that consistent or squeeze more time out of it is a no brainer.

Lithium-ion batteries work on charge cycles and are happier between 50-85% charge levels. You cannot really "overcharge" the battery because the phone will stop charging at 100% and just trickle charge to keep the battery at this level. But unplugging it after full charge defiantly wont hurt. If you keep the battery at higher levels I would't be surprised that you would get 1500+ charge cycl.es out of the phone before any real degradation which should easily get you years of good battery life. I find the battery life on the XL to be awesome and it lasts me throughout the day with still 40% battery life left and that is with pretty heavy usage.
