[Q] Insane display battery usage - Desire HD Q&A, Help & Troubleshooting

I'm on Runny 3.3 which I have had flashed for about a week.
Wiped completely before flashing (Full wipe EXT4 zip), never had this problem before.
Anyway, in this week I assumed that the battery usage would level out. I tried calibrating it, but display always takes up 93% of the battery usage.
Even on Runny 3.1 I had brilliant battery life. This problem has only occured on this ROM. I lost 7% from full in 20 minutes when I was using my phone for relatively basic tasks.
Should I reflash? What kind of values are you getting for display battery usage?

I have a solution my friend
I suffered this problem like a few days a go.
what you need to do is take a look at this post i hope it'll help

Thanks, but the link doesnt work lol

a wee bump for any help....

I changed the kernel to the Unity kernel and the display is now using 60 - 70 odd percent. Can't really test it though since its been plugged in since I flashed it. Will see how it goes tomorrow and report back

Please let me know, my battery lasts 8 hours with moderate 3 hours of onscreen time (at best)

For those who suffer this problem check out memnocs perfect battery guide
Btw I'm sorry the link didn't work. As a said take a look at memnocs guide its in dhd development page

The kernel didnt help much, the display usage has gone down but the other things have gone up lol a lot more than I expected. Will try that battery guide now.

lol what do you expect? the display is the biggest battery-eating-monster in our phone. it's completely normal that it drains that much.
fyi: my phone drains ~250-300 mA with display on, lowest brightness level, ~500 with maximum brightness level and 1-8mA in standby.
so: ~500mA/h and we have a 1200mA/h (probably less than that, since Li-Ion batteries lose capacity after some months) battery -> about 2h display on at maximum brightness

its weird because this "problem" occours only with sense rom.
On Cm7 and miui the screen was under 50% of battery usage...

Most non sense roms don't calculate ic correctly.
You can use an app called battery monitor widget to watch your battey drain if you want to.

[Q] Battery testing

I've read in a bunch of other threads that people are getting awesome battery life out of their Z or G2. Mine is okay-ish. I had a hero before which seemed a bit better. there are a couple of odd things I thought I'd check tho...
First, the keyboard backlight turns on and off at seemingly random intervals while open. Anyone else got this?
Also I've seen screenshots of the battery use screen showing how much power is used by each system. The screen always is at least 75% on mine, even when its been sat in a pouch most of the time with just a couple of messages or a phone call- this seems quite different to other peoples experience.
Is there any reliable way of benchmarking the battery to check? If not, does anyone fancy helping me test?
im actually suffering from the same problem,
i thaught it was because the first week i was using it lots thats why the battery wasnt lasting long, but on monday morning with a full charge ,
only with a few calls , texts and checking train times on TFL , by the time i got to sleep that night the battery was on 30%
I was shocked , checked the battery useage meter , everything was below 5% except the screen which was was on a shocking 80%
I Then formatted the phone , restored to default , removed everything ,
set the brightness to lowest useable which was just above the 'o' on 'ok' in the brightness screen let it charge to 100% for use on tuesday.
Tuesday - Morn before i left for work it was on 100% , the only thing i had setup on it was email, brightness on low - but useable .
Screen must have been on onliy for 20 mins throughout the day
Got home , battery was on 45%
battery useage - again display was taking over 70% of it when it was hardly on .
I am RMA'ing this one tommorow
I think its an issue internally with something shorting on the display, battery shoudlnt be draining that much if its not on
Out of interest was yours a UK Desire Z ?
Yep. This sounds exactly like my situation in every detail. I couldn't believe reports from other people saying their batteries were at 92% after 12 hours- even without using mine at all this wouldn't happen.
Mine is a UK desire z, from play.com. I think its over 14 days so RMA might be tricky, although I know I have lots of rights thanks to distance selling regulations. Hope I can exchange without too much fuss.
Ooh, just thought of something. When I set the brightness really low on mine (below 20% or so) the screen flickers slightly. It's most visible on a totally white page. Does yours do the same? Faulty backlight maybe?

Just tested mine, definitely no flicker.
Now my experience with the battery....
I play about half hour - an hour of games every day, plus about up to an hour wifi, using the xda app throughout the day using data, 10 - 15 txts and a few 1 - 2 min calls... Not too heavy usage.
I'm getting 30-36 hours, I'm happy....
BUT..... I have not plugged in through mains once yet. I read that charging through USB gives better performance... so far that is looking true.
I got the same kind of time out of my Hero using mains but that was with zero game time.
yes! pizza65 , i noticed the flickering too! , i thaught it was just my eye being twitchy ! Noticeable on internet browsing on low brightness! .
Mine was from handtec .. (amazon delayed too much) so changed last min,
it comes with a 2 year manufacturer waranty i think so even if you take it up with HTC direct they should be able to help if play dont.
I tried a diff radio and rom , but it made no difference.
Maybe the UK batch is still faulty , wasnt that the reason why it failed google testing and got delayed for release here?
Whats your hinge like ?
ddot what network are you on ?
same to you pizza65?
im on 02 , i dont think it is a network radio issue with switching of hspda/3g to 2g signals as it does say cell standby battery useage is around only 6% , but then again the phone could be false reporting

Not really if you want realistic real-world results with data connectivity etc. It varies too much since everything counts like signal strength.
You can always just turn off everything and burn the battery with a movie but first thing you should do is a few dozen full discharges before you do anything. I've noticed that HTC (and other manufacturers too) pre-use their batteries ie. charge and recharge them until they're optimal for consumers, hence the whine about bad batteries when people buy new phones (and in reviews as well).
I'm on Orange, I don't think its network because, as you confirmed, the "battery use" screen says that the screen is draining all the power. If nobody else gets a flicker on low brightness (it can take a few seconds to see it, but once you notice it...) then it looks like our screens are the culprit. Maybe.
I've deleted batterystats.bin and fully charged, so ill give that another chance before talking to play.
Ddot, what percentage of the drain is from the screen on your z? Also, if you press 'display' in that menu it will say how long the screen has been on, what does it say?
I have the same issue with battery performace. I've moved to Desire Z from my old Desire which had AMOLED display. On my old one, the display taked 5-8% of battery. On Desire Z I have minimum 50%, but ussually ~70%.
After reading that some people can use their DZs like "for two days of heavy use (gaming, browsing)" or "5% for 6 hours" I can't understand how?
Comparing to old Desire my DZ have poor battery performance. But the specs tells it must be much better.
I'll publish my battery usage stats after some days. Maybe it'll be useful.

Very interesting, thanks for sharing
And a really "geek" method here quoted from cyanogenmod issue:
Comment 27 by david.j.erickson, Aug 19, 2010
Now, I was still having abnormal drain on my battery. As suggested in the Wiki and also confirmed in another cyanogenmod post, clearing the battery stats can help. I followed this procedure:
Fully charge the battery, says Full and 100% under Settings - About phone - Status.
Reboot into recovery, wiped battery stats. Phone still plugged in at this point.
Reboot into rom, checked to make sure battery was still Full and 100%.
Unplugged phone.
Killed it, used Maps on Wifi and messing around. Killed it in about 3 hours or so.
Tried turning it on a couple times to make sure it was *dead* dead. It still tried to boot, but couldn't complete without shutting off.
Plugged phone in, booted it up. It may be better to not turn it on until it is fully charged, but this is just what I did.
Let it charge overnight, next morning took it off charger since it was full.
I have noticed pretty good battery life since doing this. This morning on my bus ride in I pretty much constantly played some Storm8 games and used Listen with Bluetooth, was only down to about 82 or 84%, can't remember. This is on par with previous CM release for me.
Not sure why this rom in particular had so much worse battery drain out of the gate, and not just for me. Fortunately it seems correctable. Maybe if a few of you could give this a try and see if it improves your battery performance we could conclusively say battery calibration is the solution.

What about the flicker? Can anyone confirm that?
I have a UK (read: QWERTY) Desire Z, first batch.
I tried reprodocuing the flicker by lowering the brightness completely and looking at a blank white page in the internet browser. Couldn't see it. Maybe I wasn't looking hard enough.
That said, I'm not getting the great battery life that most seem to be getting, and the stats always show the Display as being the number one drain. HOWEVER, it doesn't seem quite as bad as you guys are saying.
Right now, it looks like this:
Unplugged for 18 hours and 16 minutes, battery at 36%
Display accounts for 41% of the drain
It has been on for 50 minutes.
(stock ROM, running an IM client 24/7, synced to three email addresses... Typoclock seems to use 2% of the battery every time as well, which seems relatively high for such an innocuous little widget)
Yeah. I have some slight flickering too, slight when low light set.
Uk stock.
I dont think high display percent is an issue too much reading cyanogen issue comments.if you use nothing but low cpu burden apps, display should eat most.
Also if i have it off, power is eaten by cell standby.
Im still hoping for a settled battery log mentioned in forums.
My 2 cents:
If I "use" the phone, I have to plugin it every night.
If I do not "use" it (nobody calls that day, no browsing or GPS (Just work!)), I plugin it every two day (ex. mon - wed - fri).
The display is always 65-80 % of the "drain problem".
Today the stats are:
7.30 am: full chargerd 100%
7.30 pm: display drains: 70% in 1h : 21m - battery at 20%
I leave automatic background gmail sync on (only daylight, I use the "Flight mode" overnight)
No bluetooth, no wifi, no gps, brightness 35-40%

No phone either.
I'm on a North American Desire Z and I see the display using 70%-80% of the battery when I have the display on for approximately two hours out of the day. I keep my display quite dim too, at 20% brightness.
I'm also running everything stock. No root, no custom ROMs, no anything.
Isnt display percentage actually the display driver cpu time eaten?its just a theoretical value isnt it, not watts gone? It seems obvious that its eating a lot as it refreshes all the time regardless of display light level.
My screen on is only 33% today, im sure its usually higher though. Maybe its due to me flashing stuff all day. Ill do a full charge tonight and report back Sunday.

[Q] Display taking up WAY too much battery life.

I am using Super Z Sense enhanced v3.1 with incredikernel installed. I've used my phone for around 10 minutes of browsing, and the rest of the time the screens been off. It's been unplugged for 3 hours 20 minutes. I unplugged it after fully charging it and now its at 68%. The display has been taking up 79% of the battery, even though the screens been off most of the time. What do I do?
lower the display?
and every ROM displays things differently. If your battery isn't affected don't sweat it. I personally haven't run that ROM so I can't help you there.
It is on miminum brightness, and my battery is greatly affected. Not using my phone I have maybe 12 hours of standby battery life.
I'm having the exact same problem..... backlight is turned off and my display is using 79% of the battery.... I'm in cyangenMod 6.1...
any ideas?

I've replicated the results with a brand new battery from Verizon (after several charges, the capacity should be fine now) and both CM7 (Build 45 from Gridlock) and Uber Z RC2 and several different kernels. I think this is just the design of the phone, or I got two defective batteries in a row
There's an important piece of information missing here... Is your Incredible's screen the SLCD type or AMOLED type? SLCD screens don't use any more power due to what's on the screen due to the type of backlight (same light illuminates the whole screen), whereas on an AMOLED display, each pixel is its own source of light. That's why on an AMOLED display, darker themes offer better battery life as the pixels aren't having to light up as much to display the content.
Might need that info.
I have a slcd display....

I can get 6-8 hours out of a standard battery running on 3G with wifi disabled, but if I am on wifi I can get 18-20 hours...
I spend most of my time in 3g.... I'm in the nightly cm6 rom with #21 kernel now and I'm getting the 20 hours I was hoping for.... life is good.

I had the same things running Z ROM's. I switched to Myn's Warm TwoPointTwo, and the display is low, right now 7%, and same usage patterns. 3G all day at work (8 - 5), Wi-Fi all night until morning.
Maybe a phone call a day, maybe...emails/TweetDeck/texts/web browsing otherwise. It seems that that's the way Z ROM's on this phone run...?
I too have this problem on any aosp rom ive ran on it whether it be gingerbread or froyo. The display will take up a good 80 percent battery life, making my Seidio 3500mAh battery able to barely able to get through the day. However, on a sense rom the display takes maybe 5 to 7 percent and the battery will last 3 or 4 days. I was wondering if anybody managed to figure out a solution to this, as I want to run gingerbread but can't due to the battery issue.
My incredible is of the slcd type. Any solutions worth trying?
having the same issue with CM7 nightly builds... display using over 70% all the time... terrible battery life. otherwise CM7 seems very stable, thanks to all those involved in making it happen, you guys rock!
any help with the battery/display issue? thanks
Don't forget, these are percentages. Each rom/kernel combo calculates the percentages differently. Your may be getting actual better life, but the meter says 70% of the total usage because the Android System and other services aren't using nearly as much battery vs a stock kernel/stock rom.
The problem we have here though is that the battery life is greatly affected. Stock battery gets maybe 12 hours standby on a fresh install and screen mostly off. My Seidio 3500 barely makes it through a full day on any aosp rom yet lasts 4 days on a sense rom.

Sync
Another couple players in battery life besides display are frequency and quantity of accounts synched, as well as GPS on/off.
Not magic bullets to battery savings since Display is the resource hog in this instance, but you may (should) be able to squeeze several additional percentage points out of the battery by tweaking the synch quantity & frequency, as well as toggling GPS to off unless it's needed.
Mindblowing if the 3500 doesn't last a day on a full charge.
Absent that, I've read varying opinions on whether the xx.9 radio is a battery eater.
I figured out my solution. Update your radio. 2.15.00.07.28 doesn't like aosp roms, so I upgraded to 2.15.00.11.19. MUCH better on the battery life (doesn't run my Seidio 3500 dead in just one day, more like 3 now) although as a previous poster suggested, the percentages in the battery life display are just that. Percentages. The display still shows ~50% of the use, however the life has returned to normal.
Link to radio images: http://forum.cyanogenmod.com/files/category/25-htc-incredible/
And I know some of you are wondering "How in the f&$* can the radio affect the displays power usage?" To be honest, I don't know the answer to that either. I just tried this on a hunch and it seemed to work. Full day of not exactly light use (browsing while wifi tethering, some bright sun use as a navigation device, texting all day) and no forced attempts to be frugal with power (letting the screen time out on its own instead of immediately poking the power button, accidentally left wifi on most of the day, automatic brightness with a lot of full sun use...) and I'm still over 60% after 14 hours. Your mileage may vary.

[Q] Instant battery drops

Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?
Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.
Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS
That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?
Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.
Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.
Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.
Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.
so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.
Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.
Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.
figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.
FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml
Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.
Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?

[Q] Desire HD Display draining battery too much...

I've tried everything. And it seems to be getting worse, please help!
It's literally a fresh install, tried with and without JD, lowest settings, gps off, wifi off, 3g off and it's not making a difference - and it's right not to, they are optimised beyond belief and using next to nothing. The display however feels like it's getting progressively worse and at lowest brightness insists on using a **** load of battery.
VVV More info here please view! VVV
i.imgur.com/7QIYH.png
Fresh installs arent very good on battery life. They take a few days to get up to their maximum. So I would suggest to wait a few days and see what it is like then.
Any idea why? I did the wipe stats but also have had this rom installed for a week or so now.
Which ROM are you on?
And what do you mean by too much? You won't get much more than 12-16 hours out of a Desire HD unless you dont use it for much.
I get around 30+ hours depending on usage, but i don't need to charge it every night if i don't want too (but i do). But i'm not using the crappy stock ROM, but MIUI. CM7 is also good.

I'm on LeeDroid 3.3.3.
That's the thing, I barely manage to reach 12 - 16 hours with low usage; e.g. browsing news/forums - this drains the battery steadily and is depleted in 6 hours or so with lowest settings all around, making for a 'no fun allowed' use of my phone.
Typically the scenario is as follows:
Morning journey 2hr: 100% - 65%, web
Day usage 1 - 2hr: 65 - 50%, few calls, texts, web
Return journey 2hr: 50% - 20% - web
Anything after work is pretty much in the danger zone, power saver makes usage unenjoyable.
I can charge at work, not all the time, but the fact is I shouldn't have to and I am very forgetful/lazy, this phone causes way too much hassle
Could it just be a bad radio flash?

The DHD screen always drain a lot of battery, you really have to play with the screen brightness to keep it for draining your battery in a few hours.
I'm using the rom AR HD 6.1.2 and with the brightness at 35% with the phone last charged 13 hours ago my battery is at 67%, the screen drained 62% of the 33% of battery gone and it was only on for 1h9mn.
It's better than it was on the stock rom but still it could be better...

Your HOX battery life experience?

I see countless comments with people complaining about battery life not being good enough in most threads, and it being affected positively/negatively by updates.
I'm aware a lot of ROMs can have a very positive effect on battery life but I am more interested in the general overview – your battery life's life if you will! The reason I ask for your experiences is that I would like to qualitatively collect a bit of information from a fair few people and see what's to be seen.
It's worth noting that my latest HOX's battery life is exceptional and I believe it's down to a simple life/career change. It's really nothing new to someone who knows their fair share about batteries however I would be interested to compare.
So, list the times you wake up, take your phone off charge, put your phone back on charge, and go to sleep. If you can it would also be nice to know what your battery percentage is at certain points. It would also be interesting to know what hours you do on an average working week and in what sort of work environment (home/architect, office/marketing, shop/clothes retail etc).
If anyone can remember the things off the top of your head, even rough estimates just chuck then in the thread. I will then compare them all to my own personal habits.

Personally for me ICS was 4.0.4 was perfect, after update to JB it's really bad. On ICS i was loosing 1% of my battery during whole night on JB i can even loose 10% ; d. Overall battery drains faster during usage... all stock.
There's already a thread for battery stats.

Fantastic. I'm more interested in people's actual habits not stats about their battery because it only tells one half of the story. Like I mentioned this is more of a qualitative approach, so less battery stats.
I should of assumed that most people would be like more yourself so I will get straight to the point.
I have the benefit of working at home which means I can charge my phone whenever. I'm not forced to charge it over night; having it over charging for excessive amounts of time. I charge mine in the day and as a result I'm conscious when it hits 100% – I then unplug it. Other than natural degradation, I doubt I have ever damaged my battery in any way which has left me with a great battery life.
I was quite interested if most people charge their phones at night, go to sleep, unplug their phones when they wake up etc. This will severely accelerate the degradation of the battery.
well for me, ICS was bad...im using custom rom and various kernel to see which has the best battery life...all bad accept ncx 0.99....well some of the time its ok but some not...the battery percentage in ICS if not using will stay at 1% but for a 5 minute use, it will drop 10%...but amazingly, if you keep using in screen on, wifi or whatever, it will not drop that fast, well for me its ok....but now i have updated to JB still in stock, and the battery life is great.. i have watch HD movie using MX player in 2 hour and only drop 20%....when in ICS about 80%...big difference....i think stock kernel is best...
Well for me it's decent i mean yes it could be better but it's okay... heres my usage: i take it off the charge around 10 am when i wake up or so and it's off the charge till the next day morning with avarage 45-50% battery left and screan on time avarage 2:30 hours - 3 hours, sync with FB , hotmail and weather is On all the time as well is the wi-fi even when i sleep, my reception aint so great tho , around 2-3 bars top 4, 2g network, anyway my tops on the screan time would be around 6 hours with around 30% brightness idk how that guy managed to achive 6hours 20 mins on a single charge on medium brightness , could be jelly bean or maybe partitial charges ( i'm on ics btw ), anyway hox battery aint so bad as ppl may think, besides if you're lucky enough you'll get hox + battery into your hox ( 2100 ma ) which should provide avarage 6 hours + screan on time, tho i bet we could get around 8 with that battery. Hope this helps.
Ive got arhd and i got to say Im happy with my battery life, first I wasnt, when I went through a couple of charge cycles it got better and better. Now I can do 3.5 hours on screen time playing games and use it for atleast 24 hours with a mix of everything with watching videos to on the bus lol. So mines has been really good.
Battery has been pretty bad on any ROM. Now that I have ICJ421, my battery is near perfect. Yesterday I got 14h with 3h22m Screen On time.
