[Q] Intriguing Battery use.

After a full charge to 100%, my battery reports that it holds that 100% charge even through heavy usage, for up to 30 minutes. Anybody else noticing this weird easter-egg?

I noticed this too

Happened to me too. Infact, before the udate, my battery was 80%, after update and reboot, it showed 100% for quite q while and then it started dropping.

Yeah, but after that it drops like crazy.

Maybe this will help..
Remove battery stats.
Plug to the wall charger when the phone is off and let it charge for let's say 5u
Sent from my HTC Sensation xD

I've heard that it's only a good idea to wipe battery stats when the battery's fully charged, not before.

I charged the battery full, calibrated it and now drops normally. Current widget shows me very high consumption, I don't know is it works normally with dual cores.

Definately something strange going on.
I charged my phone up fully last night, took it off charge and went to bed.
This was the battery usage in the morning. Trying to work out why it shows awake and screen on for the entire time.

That's a misleading image.
What that data means is this: of all the energy expended DURING THE NIGHT(according to the photo 1-2%) the energy lost was because the phone was awake at some point, and the screen was on. It DOES NOT mean that your phone was awake/screen on all night. Just that the energy lost during the night was because the phone was awake/screen on for a miniscule portion of the night (somebody texted you or something). Nothing to be distraught over.

It seems to work for a lot of people.

i calibrated, wiped batt stats and then fully discharged and recharged, nearly a week later im gettting back to normal levels, i was also hanging on 54% for like 4 hrs then phone would just power off

[q] why does mobile data cause so much heat!!?

So i relised that when i habe. Mobole data enabled and im browsing the web my phone gets really hot 44C when i have wifi on my phoke doesnt go past 35! Battery drain using mobile data is awful to... Any ideas why?

I want this to be somehow fixed i hate the feel of it when its hot!! Causes my battery to drain more to

The phone getting hot doesn't drain your battery more... the fact that mobile data uses more power than wifi makes your battery drain more. That is also the reason for it getting warm... nearly every smartphone I have had with 3G has done this. Normal.

My dhd never got hot when using mobile data
Sent from my HTC Sensation XE with Beats Audio

Neither did my Hero.
This sucks. My Sensation apparently can only browse the Internet using mobile data for 2.5 hours before the battery dies. I'm pretty sure that's not the case for the SGSII either

My sensation gets pretty hot to, but that wouldnt be such a problem if the batterylife would be good. At the moment my battery drains about 8%/hour when it's idle... so i have 12,5 hours stanby time! that sucks -.- I'm gonna get a Anker battery soon and hope it's gonna get better with that...

If you get 8%/hour drain while idle, and truly idle (i.e. your phone is truly in sleep mode) then you've a faulty model - bring it back

Well i don't know how it was with the stock rom and anything. And i don't have any longtime informations with custom roms, kernels and so on, because i just recently flashed a cr.
But today I unplugged it at 8:30am and it had 100% at 10:30 it had 84% and now it has 70% and from 8:30 to 10:30 i was only on facebook and surfed a little for maybe 10 minutes or so :S
Now I flashed Bricked Kernle v.1.5 i hope that its gonna be better with that.

Do you know if you're phone is actually sleeping when the screen is off? To check, go Settings - About Phone - Battery. Here you can see Up & Awake Time, but to see more accurately, click on Battery Use, then click on the graph. Look at the Awake bars and make sure they correspond to the Screen On bars.

The screen on/off and active bar are almost identical. There are some little tiny active times when the screen is off, but thats probably some syncing...

Faulty model, return it! On (real) standby (which the image shows you have) you should get only 1-2% battery drain, even on Sensation

Don't think that's true.
For one, there was a few weeks when my phone did not heat up like crazy from normal usage and I could make it last 2 days. Then one day it started heating up like crazy... also plenty people report 2 days battery on moderate usage with Sensation - i.e. no crazy battery drain.

Could it be that my phone is alright and only the battery is faulty? It would suck to return it -.-

It's not a faulty model. There are no known issues with standby drain on any sensation.
Notice the image shows times with poor signal too. Additionally he may have auto sync handling too many accounts.

It's getting better with the ROM I'm using at the moment and i orderd a Anker battery. I hope it's gonna get even better with that beauty

I can't explain any facts, but I really don't think slightly higher battery drain is because of a faulty phone. I've owned two Androids and tinkered extensively with many, many others. Most Android phones seem to be awake similarly to that one user's battery graph. It's normal.

Battery getting worse day after day.

Well, for the first days the battery life was great, going on almost a week and the battery life is bad, just as bad as other phones. The phone with regular use would by 9pm have aprox 40% left yesterday had 30% no today I am already getting a warning of low batt and use was normal...wow....this is not looking good

Just curious...what apps do you have under your "Accounts" area in Settings set to sync?
What apps do you have running persistently (check your notification drawer)?
Screenshot of your battery usage?

my battery is low or around 30% at 12am when i sleeep sooooo

Out of habit I plugged mine in via PC USB for an hour (charging it an extra 50% from 8%) but according to my battery stats I'm rocking nearly two full days (1d 22h) from 100% with only an hour plugged in while gaming....with me being in an area with one bar to no signal for over 10 he's today. My GS2 couldn't do that .

Edit: oh, and I'm still at 42% typing this ;-)

hmm, rogue app that you installed??
mine has been great since day 1 with no hiccups. 15hrs or so with 3+ screen time yields me about 25% battery left at end of the day

Yeah, not really impressed with the battery life either, barely make it through the day with moderate use. Screen is a killer!
Sent from my HTC One X

17h 30m with 52% capacity left after moderate use today (2 hours reading the news with various apps on LTE/4G and the rest of the day on WiFi, with maybe an hour browsing, updating apps and fiddling). CPU - 7.05% at 1.5 GHz, 4.85% at 1.13 GHz, 3.07% at 810 MHz, 80.64% at 384 MHz with the remainder of CPU usage scattered in between. Pretty good really - much better than my HTC Desire.

Use BetterBatteryStats and check for rogue apps sucking battery.
After that, if your phone still is dying incredibly quickly, just use the phone until it dies. Then boot into hboot (volume down and power button together, a white screen with blocky text and some androids on the bottom will show up), and keep that open until the phone shuts off again. Then do a full charge to 4.2v.

Try a number of battery saver apps / tips

I had a Desire, have a Xoom & now a X. Found with large screen devices you have to use those normal tips such as screen brightness, rougue app killing, sync for FB / mail. Rooted the HTC when first purchased with Leedroid to fix battery. Got 50% more from just that process. Didn't wait for the first OTA upgrade to fix that first horror release. Suggest:
a) batterysaver (or similar) on all devices - I reckon it gives a little %.
b) Turn off all apps not being used
c) Turn down screen
d) Turn off Bluetooth / GPS / etc when you don't need them
e) In car, at work, use charger
Gotta love smart phones. If you use it, you will lose it. (Battery that is).

- Root it and remove all the bloatware.
- Turn off auto brightness and set it at a fixed level (minimum is too dark, I have it set a little above minimum)
- Only enable wifi/gps when you need them
- If you need sync, turn down the syncing intervals
I get great battery life on this thing. There must be something you are doing. What do you mean by 'regular use'? Are you playing games for hours on end?

I seem to be having the same problem. Last screen shot I had I was at 37% with 16 hours. Now I'm sitting right now at 40% with 5 hours. Not sure what's sucking up all the juice. I don't have any sketchy apps installed. Might delete them one by one see how that goes because something is seriously draining the battery and I know it's not normal.

Turn off auto brightness if u have it on. My battery is amazing, even at full brightness, but auto is too agressive and drains more that it saves

my battery was horrible. In fact I went to take it back to att. He told me to try a complete factory reset and try it factory without any extra apps installed. So I did and my battery is sooo much better during my "test" before I couldn't get more then 9 hours with 3 hour screen time but now look at it. I'm guessing ny case it's an app like task killer or something I had on the phone killing the battery. Now to figure out what it was.
Sent from my HTC One X using XDA

I just got over 36 hours on one charge and had 16% left. That was riding a motorcycle for 3 hours through the mountains where I know there is spotty coverage plus a 2 hour conference call on Friday.
One thing I've noticed, check your wireless settings and make sure Best Wi-Fi Performance is unchecked. I had that turned on and got about 9 hours on a charge. Turned it off and fantastic battery life.

Yea there are definitely some rogue apps that will kill your battery. Best bet install an app one at a time and see which one starts affecting battery life.

Are you guys rooted or flashed a different ruu? That would be nice to know, and how many emails, brightness etc. I've been on my phone for 2 hours or so of screen on time and its at 34%. My brightness is set at 20% and I turned gmail sync off. When I charged it to full this morning it was only at 4.177 is that normal? Some people mention that theirs is at 4.2.

i'm with you. I have seen some posts on here about 4.2 and noticed some say 4.3 should be achievable. Perhaps they are rounding up the 4.177 to get the 4.2? I, too, charge to exactly 4.177 in morning on full overnight charging. Actually, my device is 4.187 until i unplug, when it immediately drops to 77. That said, my battery life has been great in the 9 days since my initial day or two with the phone.

horibble battery life

So I've updated my phone to the latest trickdroid 6.2.0 for the TMOUS version, and using it for the psat 3 days, I've realized how bad the battery life is. I only turn on my data when I need it, maybe 20-30min max per day. I text occasionally, and by 6pm in the evening, it needs another charge from the morning. ATM it is 36%, with 11hours on battery, which is pretty bad, screen is at 51%, cell standby 23%. I mean I'm not even using the phone much. What can I do to fix this, I also have Juice Defender installed and it seems without it, my battery would be dead within 6 hours.

That's decent for this phone. Try CM10 and see if you make it to lunch.

With eleven hours on battery and a little over half of that being screen time I'm going to say it's right around five hours.

I currenlty own a T Mobile USA branded One S (black in color) and one of the very first things I noticed was, the battery life was significantly less than my international One X. On average, I would have close to 15 hours with my One X (approx 4 hours of screen on time). My One S gets about half of that. I've been able to drain the battery (completely depleted from 100% down to 10%) in about 6 hours with the same exact usage pattern as my One X.
Weather, Twitter, FB updating every hour, email (2 accounts) every 15 mins, lot's of YouTube, Web browsing, texting quite frequently. I was actually surprised with my One S. On average, I get nearly 10 hours (give or take an hour) with approx 2 hours of screen on time.
Interesting to compare and see what other's are experiencing.
Best.

i have about 5 hrs of screen time and my phone running for almost 37 hrs. with 1 hr temple run, 2hrs music, 40-50 msgs and 30mins wifi ...!! seems pretty ok to me !

Wow! Very nice...
Custom rom or?

I have nice battery life on stock and all custom ROM. OP: have you researched what a wake lock is and how to interpret the battery info in settings? Do you have the S4 or S3 One S?
As to the difference compared to One X, the One S will fare much worse when displaying white and bright colors because of the AMOLED, but besides that in theory be a bit better all round.
Edit: I see you have the TMOUS so I assume S4. Also 21% seems high for cell standby, are you in a bad coverage location?

[Q] Please Help!!! Battery shoots up automatically.

I usually flash custom roms on my device. But my device has one unusual behaviour. When I charge my device and suppose it is 70 percent charged and I reboot my device within 20-25 minutes, the battery level shows fully charged. (100 percent) After that the battery drains within 2-3 hours. Because of this I charge my device 3-4 times everyday. This happens on every custom rom I install on my device. Should I change my battery or is it the device's fault? Please help.

the percentage increase after reboot is a htc common issue while charging
about the fast drain maybe your battery is dying or doesn't makes contact properly
check it

Thanks for providing this useful information. Do you mean using paper or something that holds the battery tight or I misunderstood something.

exactly that
use something to hold the battery and see if you still have reboots

Actually I think the paper solution won't work. He's not having reboots, just the battery is draining fast. It looks like that your battery is almost died. I think you should buy a new one. And I highly recommend Anker's one.

Thanks once again. Will try.

I didnt want to make a new topic but I have similar problem:
i switched from standart ROM to Cyanogenmod 10 nightly builds for my Sensation Pyramid (original battery, about year old).
Everything worked fine, but there is one more than annoying problem:
I charge phone to 100%, i pull charger out. If i use standard things on phone (settings, gallery etc) everything seems to work fine. As soon as I enter any applications (Twitter, Facebook, default Web Browser) it just shuts down in 20seconds or in 2/3 minutes (always some random time, i can browse web 10 seconds, it shuts down, sometimes i can do the same for a minute and then it shuts down), it doesnt reboot just shuts down.
When I turn it back on, it shows battery level ~ 9-15%. It was 100% just 3minutes ago. I charged it for hours before, so that 100% should be real. I tested with battery drain monitoring app, when i use any apps, battery drops for like 1200% every minute. Its Ok on standby mode.
When i just reboot the phone, it comes up with some random battery percentage, f.e 47%. So it can go from 100% to 7% and after reboot it goes to 47%.
I thought it might be a ROM problem, so I installed this albinoman887 ROM http://forum.xda-developers.com/showthread.php?t=2115520
Did factory reset, cleared cache, phone was 100% charged. But the same problem.
I dont thin its battery problem, because it was OK with stock ROM. Is there anything i can try to fix this problem without going back to stock ROM (or other Sense based ROM)?
Here is a screenshot from my "About phone" section:

Really no advice on this?
Im not so good with Kernels etc., but my guess is- maybe this has something to do with CPU usage? I checked with CPU Spy app, it says Internet explorer, other apps use 1566MHz. Isn't that too much?
