Hi, fellow SG2 owners. I have been experiencing something that I consider unusual, and I'd like to resolve - if possible - what I think is an issue/a bug...
A couple of days ago, I accidentally dropped my phone. It kind of flew right out of my hand. The SG2 was protected with a silicone case, and in addition to this, the floor was carpeted. I guess the the phone must've landed on a weak spot, because despite the case and the carpeted floor, my phone restarted itself.
After this unfortunate event, the phone has, as far as I'm concerned, restarted itself once (excluding the reboot that occurred right after the impact), despite being in standby.
In addition to this, the battery graph often shows vertical drops, which seems kind of weird. They mostly occur even when I'm not using the phone. I think they might be related to random reboots, but I'm not sure. (See the attached picture. There's a vertical drop in the first hours, and one at the end).
I don't have any applications that drain the battery life more than normal.
Has anyone else experienced something similar?
Do you think the random reboots and the vertical drops in the battery graph are related to the accident I had?
I'm going on a three-week-vacation to the States in two days, and I'd really like to resolve this potential issue before my departure.
I experienced this vertical drop too a few hours ago! My phone wouldn't unlock itself and seemed to be off (even though I never turned it off) so I took the battery out and put it back in. The vertical drop happened right after I turned my phone on. First time it happened to me. I posted a thread about my problem too.
Looks like reboots to me. If it drained while properly booted it would have been a continues line. Not sure what it means but your phone signal changes at the same time as the drops.
Let your battery drain till the phone turns itself off, the charge while off till full. It might help.

I appreciate the response, guys.
By the way, I haven't inserted my sim card yet, so there shouldn't be any phone signal at all.
Yes but the signal line shows a yellow line (instead red) at the same time as the drops.

Yup, that's why I think the drops are related to the reboots.
Is it possible that these reboots and battery drops are aftereffects of my accidental dropping?
does anyone know how to manually refresh the battery graph? Mine seems to refresh every 10-15min and sometimes longer. Any way of making it real time to match the time up the top vs battery graph time?

Me too
I've been getting these too and I've never dropped my phone. On occasion it has apparently entirely drained the battery. And it is always when I'm not using it. It's a bit like playing 'what's the time Mr Wolf' in that you have to catch it in the act. I did catch it once doing this and it was, to all intents and purposes, dead. Wouldn't turn on or off, only revived by taking the battery out. Once rebooted, the battery cliff was apparent on the graph - i'd just caught it before it completely emptied. I was advised to empty the battery and then charge it with the phone off for 8 hours and certainly the next day it didn't do it. But now I'm getting little drops creeping in again. Battery life isn't bad actually, I'm on 20+ hours at the moment, with one 10% vertical drop and two 2-3% drops in there. Strangely last night, the graph crept upwards.

Hey guys, I just got my new GS2 this afternoon and i'm enjoying it a lot but there is a HUGE problem: the battery! I've been charging for the last hour or so and the percentage has only gone up by about 10% also, the entire phone is really warm/hot especially for doing simple things such as checking email and browsing android market. I checked the battery usage stats and it says 57% is due to display! This is even though I set the brightness to the lowest possible, turned off auto-rotate, no live wallpapers, no animations, etc.
Has anyone else had this problem/know how to fix this? Thanks a bunch.
Try shutting it off and take the battery out. After it's cooled off some put the battery back in, turn it on, and try charging it again.

Just tried what you said, didn't work: charging for 10 minutes left it still at 67%. I started charging it at around 5pm or so at 28%, and now it's 9pm at 67%....what gives? that's an average of under 10%/hour.....

Sometimes first charges can take awhile. You won't be really able to tell if there's an issues until after a few charge and drain cycles.
Not an answer you're looking for I know. A draw back of a new smart phone.
But keep an eye on the heat. Download a temperature app so you can check to see if it's getting too hot. 50+ celcius is not good. Can damage the battery at those temps.

Thanks for the information, didn't know that the first charge was any different from the other charges. Right now, I have a fan just blowing on my phone so I think the temp should be fine for now
Lol not sure what happened here.
I left my phone off charge to take a shower at 60%, came out and it was 20%?
Im on MIUI Rom 1.11.11
Is it just bad calibration or something?

Did you also see a significant drop in raw battery voltage?
Most likely the fuel gauge just glitched or reset. 40% in 20 minutes = 2 amperes drain, our device simply can't pull THAT much current, not even close.
Does if really equate to that much? I have seen a few cross ROM battery complaints ND I'm pointing my finger at the Facebook app

Fastest ive had mine drain down is when I left PocketCloud logged into a VNC session. It will run it down close to that fast.
Ya, Id take it off teh charger, reboot and see what it says after that.
When I was running CyanogenMod 7 this would happen all of the time to me. My battery would be at 98% and then suddenly after about 5 min, it would read 50%. I'm not really sure what caused this, but CyanogenMod 7 is the only ROM that I have had this issue with.
I'm now running Miui and I haven't ran across this issue yet.
I did read that calibrating your battery should solve this issue though.
Possibly similar to what a few of us encountered here: http://forum.xda-developers.com/showthread.php?t=1325164
It had to have been pretty hot to draw that much current that quickly. It's a 1650mAh battery. It will provide 1.65A for an hour from fully-charged, until it is discharged. You lost 40% in, say 15 minutes. That's 160% in an hour. Or about a 2.6A rate. Nearly 10 Watts. Sammy spec's a 9 hour talk time rating on 3G. By comparison, this means normal battery usage during a phone call is about 0.18A. Think about how warm the phone gets during a call, and compare that to how warm it'd have to get if you were sucking juice at 14x the normal rate.
If it wasn't really hot, IMO, either there's something wrong with the battery or your issue is "cockpit error".
Minds did the same thing today. I think it was from a old theme I applied.
After the theme was converted my phone started acting funny.
The screen started to lag
Phone got extremely hot without even being touched, just laying on my bed.
Phone kept rebooting
I didn't have any of these issues until I added the theme

It did happen to me too, I just added a new theme (GOlauncher app) and the phone has started to get hot without using it, and the battery goes down very fast.
Isn't that a little bit sad?
Since the support for this phone is realy crap.
I have the issue where the bat does not charge to 100%.
I have to remove the cable when it hits the green LED (99% full) and reconnect it again (LED turns red) to get to 100% finally.
When I contact HTC they tell me to send it for repair.
Buit this is obviously a software issue, not a hardfware issue.
An update would fix it easily.
My GF has same issue, and I swapped tyhe phone at the store in the first week because of this. New phjone exactly same problem.

Normal behavior. And if this is the only issue you are having (not really an issue) you are doing pretty well. The phone has a built in overcharge protection (as all phones do) that will charge the phone to 100% or just under then let it discharge to 90-95% and then charge again to 100%. There are SBC kernels for other phones that will change this effect by charging to 100% and then trickle charge it to keep it at 100%, but none made for the EVO3D because it really doesn't seem like a huge deal. And if you are really sending phones back over 1%, you are one picky dude.
I think your thread title is wrong. There are some great fully functional ROMs out there.
The battery will fluctuate from 95%-100% while on the charger. Think it's an HTC issue, or maybe Android. This isn't something to get all pissed off about IMO, maybe I am missing something though.
yep.. is 100% normal.
i'm running on a shawn3d 1.4 rom, with a akernel v10.07, have a battery life of over 2 days, with bluetooth and wifi on, medium use..
everything but I mean everything works..
so euhm... whats the problem again???
OP,
Why you butt hurt?
Just kidding. These issues are all normal for android phones. I have seen these issues on the Heroc, OG Evo, Samsung Epic and now Evo 3D.
It is not that I am picky.
You must agree that it is quite anoying if you sleep for 8 hours while charging, and you then see a green LED, but then to see 99%.
When you for instance have the alarmclock ringning, you drain 2 or 3%.
It is not normal behaviour I think. PLus bat-life was 2 days in the first 2 weeks, now I barely last a day.
Any thoughts?
Edit...: 3 HTC phones before NO problem at all

There is no such type of issue on my evo 3d. I've tried around 15 different ROMs and all were functioning as they should.
The issue you have posted is not an issue. If you see green LED and numbers below 100% then your phone went to 100% before but you havent noticed that. I advise you to keep your eyes on the battery icon when the LED is red and % are near 98-99. You will notice it goes to 100% and red LED turns green. Then the numbers will go down as your battery discharges.
It is an overcharge protection made by the manufacturer.

What ROM are you on? Try a custom ROM for better battery life. I'm using ViperROM and plenty of people provide screen shots in that thread of their own findings (e.g. ridiculously long battery life).

You want your battery percentage to stay at 100 when you charge it? Get rid of your 3d, get an evo 4g, put a froyo ROM on it and use a sbc kernel. Other than that, quit *****ing. Like others have said its a built in over charge protection from HTC. Some may argue if its actually needed because i used an sbc kernel on my old evo ever since it was available and never had a problem with my battery. But is like 3-4% really that big of a deal?
Saying that there are no fully functioning roms is a bit rude imo, there are tons. I use warm 2.3 and it has zero problems.

It's not a issue, it's supposed to be that way. It has a "maintain" function once it reaches 100, it will let itself drain back to 95, the charge back to 100, then back down, etc.. It's to maintain the battery correctly .
Dumbass with a smartphone.
It's not an issue you idiot. It's so your battery doesn't die for good after a short amount if time. They're not supposed to be fully charged like that. Educate yourself instead of looking like a fool.

If a lithium battery were brought to 100% and the charger kept charging it to keep it at 100%, you would have far worse issues than a 5% fluctuation, you would likely have a house that has burned down. Lithium batteries are very picky about their voltage, too much and they go into a runaway exothermic condition and become fireballs, too little and they go into a runaway exothermic condition and become fireballs.
Check out youtube videos about damaged or overcharged lithium batteries.
Honestly, this is a problem with all Android phones, I've gone from the EVO 4g to the E3D and I've had the same issue, though I wouldn't exactly call it a "problem"...
What I do when I wake is unplug my phone, check my email/social networks on it for a few minutes, let the battery drain a few % points, then plug it back up while I shower. It sounds weird, but unplugging and re-plugging really helps, as my battery then stays at 100/99% for at least an hour after I leave my house before beginning to drain.
I've noticed that if I don't do this, the battery drains a lot faster than it would if I had...
Hope this helps
yea it is eternity 130
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

I'm contemplating returning my phone just in case of a 'bad batch,' but I'm afraid I'll get a phone that's even worse lol. I can't forever replace phones. I'm just trying to make it work.
Does this phone have the ability or need to reset battery stats? I know you couldn't do it, or it was unnecessary on the SGSII. Just curious if it's a calibration issue.

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.

The one thing I've notice about my phone is that when looking at my wireless icon in the notification bar, there is something transmitting 90% of the time (download it appears as it is just the bottom arrow blinking). It does this even when sync is turned off. I've gone through the phone and I can't see any app running. Has anyone else noticed this?

My replacement phone literally just ran all night. I had been awake backing up my system with Titanium, and it stalled before I went to bed. TB kept my phone running for 8 hours straight with the screen on and my phone is only at 18%.
If your battery life is ****, return it. Currently running Stock, rooted and unlocked with dormancy fix.
