Battery Life in WM6.1

I've been seeing sporadic posts in different threads about battery consumption in WM6.1 ROMS.
Well, it turns out that since starting to use WM6.1, I've noticed a dramatic decline in my battery life. I can maybe squeeze out a day of use with minimal use. If I use HSDPA / Voice / WiFi - forget it, I get 1-2 hours before the battery drops to nearly zero.
I used to get much better life out of my battery before.
I tried playing with different ROMs, then different Radio version - to no avail - battery life sucks.
Any tips / ideas / comparisons on how to get reasonable performance with WM6.1 or is this just my battery having issues?

I think this would be more your device...
To check this, go back to your manufacturers ROM, and see if the same still happens. Also try this test with no 3rd party applications installed.
Poor battery life is usually cause by either:
1) Applications using 100% CPU
2) Faulty ROM
3) Faulty Phone or Battery.
If you're tried multiple ROMs, I'd say you can rule out #2.
I get around 2 1/2 days out of the stock 1350mAh battery on my hermes.

Hi
ygeller , i had some battery life problems with my hermes and i found on another thread some ppl saying to first flash the ATT rom RUU_Hermes_CINGULAR_WWE_3.62.502.3_6275_1.54.07.00_108_UOOS_SVN05_Ship
and then the cooked one. That worked wonders for me, the radio version 1.54.07.00 is the best i tryed so far for battery life and network stability.
I'am using the latest PDAViet rom and no problems so far, with battery holding for 2 to 3 days with normal use.

Please try another radio, i used always the newest en I got the poorest battery performance! Now I use 1.47.30.10 in combination with PDAVIET roms and now my battery holds a day of 2/ 2,5!!

u are not alone

I have issues with charging too with my phone never charging full no matter how long i keep the charger on it get's stuck at 80%...
But good news is that I've arrested the drain now i flashed the PDAcorner pr0 V3 yesterday and through the entrire night the drain was less that 1% but it hasn't solved the drain if I use voice/data cause an 11 min call had my battery coming down from 63% to 16% ..
I guess i am gonna try and flash the stock ROM as compumad says..
I guess at least the charging issue is due to faulty ROM ( i hope)..
Thanks guys for input..

I agree that I get better battery life with the 1.47.30.0, in addition to aquiring a signal faster. The BIGGEST fix for me however was replacing my year old battery with a good quality Li-ion battery. Now I go a full day with hardly any drain using anybody's ROM, of course YMMV

I am having the same experience. I tried several WM6.1 ROMs and they always drained the battery within 1 day. I am back on Schap's ROM now and I can work for up to 3 days with HSDPA and BT on. About 1 month ago I returned my Hermes because of a defect and HTC replaced the complete inner life of my phone. So this can be compared to a more or less new Hermes.
As a comparison, I recently received a Wizard as a gift and flashed it with the WM6.1 ROM of SNN and believe it or not, the battery lasts for amazing 5 days! And that is with GPRS and BT on!
So, are we talking a major device issue, a ROM issue or is there something I'm missing here?

I've been on the current Shamanix`s WM6 Ultimate v2 FINAL [SuperStorage] ROM for a while and indeed the battery drains very quick- I've had to schedule Exchange email to be on for 2 hours now but a simple 20-30 min voice call drains the battery by about 30-40%!
I was on Schap's ROM but was waiting for his latest update. Will have to consider another one.

I have also had the same issue as people here with the battery running down very quickly.I did try going back to schaps 4.31 but did not seems to make a difference anymore.Will try going nack to standard rom and then changed to cooked and post if there is any difference.

are u guys serious? 2.5days out of the stock battery?
my battery is a 1300mAH and i get a week and a bit on standby, constant txting wifi, screwing around, i get at least 4 days.
now that i have a 1650mAH i cant even kill it in a day (wifi bluetooth and gsm all going at the same time)
theres a 3000mAH battery coming in the mail, if im gentle with it it should last.... 0.5 months?

you need to resync your battery circuit, charge your phone till your phone cant charge it anymore, then drain it till you cant even turn it on (no lights at all), charge it up again and it should be reading correctly.
here is more info about Li-ion and Li-Poly charge circuits.
see subheading "Guidelines for prolonging Li-ion battery life"
http://en.wikipedia.org/wiki/Lithium_ion

I also had a severe battery drain with several 6.1 ROMS. My main culprit was caused my certain applications not closing properly and running at 50%-100% CPU. The main apps were Internet Explorer, Windows Live, Poutlook, basically network based apps. For some reason the app wouldn't show up as running. It wasn't until I got a new task manager that showed "processes" that I found the culprit. I would make sure all these processes were "killed" and my battery life lasted a lot longer.
I eventually went back to a 6.0 ROM, as I couldn't take all the problems.

Unfortunately, I've done that without planning. I am constantly fully charging the phone - then it drains and dies after a few morning phone calls...
This doesn't help...

OK. I am flashing the ATT ROM to see what gives.
Already it's been a chore. I haven't flashed stock ROMs in quite a while - had to extract the NBH file and use in with a cooked ROM wrapper to get it to flash.
Will report back with results.

Have Flashed ATT, then PDA Corner Pro V3. I didn't have much faith in the voodoo of flashing the official ROM to magically repair stuff - and so far I can't say that I've seen much change...
too bad...

You put PDA into bootloder mode and the flash, no need to jumpthrough hoops.
Actually the AT&T Official has repaired numerous bad flashes for me, is a lifesaver.

I have been a user of the stock AT&T WM6 Rom for many months. Before that, I had the stock Cingular 8525 WM5 Rom, and many of the cooked WM6 ones, starting with an early Black, a couple of Custel's, Sleuth's, and a few others. I now use personal derivations of the stock AT&T WM6 Rom that I have been cooking up over the past few months.
I have NEVER had good battery life on my 8525, with ANY ROM at all. Left alone, my battery dies after only a few hours. I have learned to live with this, always carrying a second (charged) battery, and I have chargers at home, at work, and in my car, in order to deal with the issue.
I must ask, when others say they get 2 or more DAYS out of a charge with "normal use", please define what "normal use" is for you.
My "normal use" includes checking 4 email boxes, one of them push, one at at 30 minute intervals, and two hourly. I use PocketWeather, which I have doing updates at 30 minute intervals for 4 locations. 1-calc updates monetary exchange rates daily. I make/receive only a couple of phone calls daily (yes, a BIG battery-killer), and I rarely receive text messages. No MMS at all. I utilize Bluetooth devices during my commutes in both directions, only use WiFi at home (another big battery drainer, but since I'm at home, it doesn't matter). I keep the IR port turned off unless I'm actively using it. I am on the internet with my device every chance I get, using the normal AT&T WAP access point with an unlimited plan.
I feel that with the amount of usage I get out of my device (especially Internet and emails), I can accept the poor battery performance.
But I am curious ... those of you who claim much higher numbers for battery life under "normal usage" ... please explain what "normal usage" means to you. I have never seen anything close to the numbers that have been posted by many.
FWIW, my two batteries are: 1 stock 1300mAh, and one is a Boxwave 1350 mAh. Both are well over a year old.

I'm forced to agree with pvs. I'm in a very similar situation: I use the stock AT&T WM6 ROM, although I've used a couple of other ROMs and Radios before this.
If I set my 8525 to auto-poll my 4 mailboxes every 15-60 minutes, I always notice a definite decrease in battery life. In the beginning, I'd get the "low battery" notification before I even left work late in the afternoon (this is after getting a full charge the night before). In between then and now, I turned off auto-polling. I couldn't get any new mail unless I did a manual send/receive...but my battery life improved dramatically; I could get nearly two full days' usage out of it before having to charge at night.
I was fairly confident it had something to do with that data-connection required to update the mail, and I feel that it's confirmed: 3 days ago, I found a registry edit that turns off the 3G/data connection after being idle so many minutes (I have mine set to 2 mins). I can now auto-poll my boxes, but my battery life has decreased again...not QUITE as bad as before, but I pretty much have to charge it every night, now.
(Additional "normal" usage for me has always included using Bluetooth for a headset and several calls during the day, varying in length...around 30-50 minutes total talk time, if I had to guess.)
Frankly, I'm surprised at the people who say they're able to leave their data connection on all day (even if it's sending no data in certain moments) and see no appreciable battery-drain. This is my second 8525 and second battery, and my experience has remained the same.
I was going to try and find some sort of push EMail solution...but to make matters worse, I've been doing research and unless I'm misunderstanding things, it looks like WM6's version of "Push EMail" requires that "constantly-on" data connection. I'm frustrated, and I'm seriously considering getting a Blackberry.
If someone can come up with some alternative ideas, I'd love to hear them, but...even though I love my 8525...my patience is starting to wear thin with it.

Good grief. Is this the consensus of everyone? I'd hate to give up my 8525, since it has Windows Mobile versions of what I work with, plus some pretty nifty games and apps...but I want a device I can both work AND play with. So far, the 8525 is falling down on the Work/EMail end.
I've dodged the blackberry for so long because of 1) no touchscreen, 2) it lacks the versatility of a true PC (ideally, PCs can be used for work and play; blackberries seem meant primarily for work). Plus, I don't know if the Blackberry's "push" EMail features will work any better with my particular mailboxes (i.e., it may have to constantly "poll" those boxes as well, which may result in similar battery drain).
BTW: It's noon here, after 3-4 calls this morning (around 25 minutes or so), EMailboxes updating (2 at 30 mins, 2 at 60 mins), Bluetooth off, and having read 2 CNN articles (and closing it right after)...my 8525 is at 70% power. X-(

Fuze:Android vs WinMo 6.5

WinMo 6.1 was almost unusable. I switched to a Tael ROM to run 6.5, which was immensely better, especially using Spb Shell 3.5.
How does Android 2.1 compare? I know its a work in progress. I know its better than WinMo 6.1.. but how does it compare to WinMo 6.5 on the Fuze?
Also, I see mostly Android CDMA work being done for Raphael--anyone actively working on the Fuze (GSM) version?
thanks,
RickH

Actually, most of the work is being done by devs with GSM devices. You probably see more CDMA posts because we have more issues Or we're just special ed, either way.
I love Android, but currently it's not a replacement for WinMo - for me. The main reason being the battery life. While the devs have done great work, the battery is just not up to par - I need to run a full day on idle at least before I can switch over to it.
Is there any reason you haven't given it a shot yourself? You don't flash it to NAND, the entire OS just sits on your SD card - literally nil chance of breaking something hardware-wise with the device!

guess it's worth trying
I just need to find the steps and the latest usable build..
Battery life is that great on WinMo 6.5 either.
Often I find apps that I thought I closed are still active. Now I always check whats running before I put it on standby.(hmm wonder if there is an app to autoclose everything and standby the phone..)
BTW, I found when using the GPS in remote areas putting the phone in Flight Mode works wonders for battery life. GPS stays on, but Bluetooth, phone service, WiFi, are all off.

If you're in an area with poor or no service, turning off the radio will certainly increase performance - one of the main killers of the battery is the phone's radio. If it's constantly searching for a signal or using a lot of power to keep one... you get the point.
Battery life in Android is not on-par with WinMo. At least not for CDMA devices, some on GSM report 10-12hrs of battery life.
Were you having an issue finding builds? http://forum.xda-developers.com/showthread.php?t=601751 - that thread, first three posts or so have all the stuff you'll need.

Ive found that on my fuze, winmo 6.5 is horrid, but its got the only reliable battery life i need. I text like 24/7, so on android my battery is gone in an hour or two, while on winmo itll last atleast 8 hours, as long as i got my wifi off and got my screen's brightness turned down.

From one fuze owner to another. I have been running android 100% since GPS was enabled and don't plan on going back!

100%, seriously? how can you keep the battery life all day long? do you have 2 or more batteries as subs?

I have made it on my touch pro at&t！

i got about 3 hours on android, 20 txt messages, about 5minutes on the internet via 3g wifi and gps off, back to the blackberry for now

I like the stability of Windows Mobile, however, I hate not having ANY applications worth downloading.
I have been running Android on my Fuze for the past few days and am EXTREMELY surprised at how well it operates. It is honestly faster than my G1 and more responsive too.
The biggest downfalls I would say, are the lack of camera, poor battery life, and it gets pretty hot.
I honestly wasn't expecting for it to run smooth at all, but was delightfully proved wrong.

sorry about getting back so late on the reply but I just keep my phone charged as much as possible. Unfortunatly with the new stuff(6/21) the battery is a mega killer so back to winmo untill a more battery friendly build comes out. Allthough I did catch a glimps of a new HTC android phone on AT&T shelves yesterday. Tempted to get it for the low low price of $129.99

G2 Instant On

So they are showing the instant On , on the new desire z in london which is basically is same as tmobile g2 here in states.
i was wondering is it something to do with SSD beign used or are they using some kind of hibernation technics in which phone is not entirely turn off instead goes into hibernation and then come back up.
and if its gona be possible to use in other android phones.

Realistically speaking, all phones use "SSD". SSD stands for Solid State Drive, and I doubt there's many phones out there that actually use a standard hard disk as storage.
All data is stored on flash chips, but technology in that area, whilst great at shrinking and increasing capacity, doesn't really improve super fast in terms of data transfer speeds.
I suspect they are doing some kind of clever hibernation as already suggested. Like it loads up a CPU state from memory that is stored when the system is shut down. I imagine first time out of the box will still be a good minute or so as usual, but successive reboots will be a lot quicker.
I imagine there will also be some sort of button combination you can press on boot to do a "fresh" boot rather than loading the hibernated version (for the usual reason that people reboot - to flush memory etc).

but the question is will the g2 get it? maybe instant on is just something built into sense. keeping my fingers crossed

Hopefully its available for the US version. Would be a neat lil way to conserve battery power. Devs will find a way to port it.

I expect the G2 will get it as well - Looks like more of a ROM/SPL feature than Sense. Incidentally, I saw another video yesterday which showed a much more usual boot time. In the region of 40 seconds or so.
My theory seems to stand up to this. It's possible that this was the first time that the particular handset had been booted.
I'm not sure where the battery savings would come in. Aside from the few seconds shaved off when booting I can't see much other saving. In fact, it may transpire that the "system image" that it stores is held in battery-backup storage, which may in fact drain battery more, not less.

The same way sleep mode saves electricity on desktops.

it would save battery in that you would be more likely to shut down completely when not using it if it booted up that fast. right now I rarely shut my phone down because if i need it in a pinch, I'd have to wait forever for it to boot.
edit: @dazultra2000, that's assuming it's a real shutdown rather than a hibernation as you suggest. you're right though, it's more likely to be more of a hibernation type thing. but still, if it used more battery than it saved, then what really would be the point? there would be no advantage over just turning the screen off

It would have to be a hibernate/sleep thing. It would be great. To me, it would not be useful if it doesn't notify you of a message or call right on the spot as if the phone was on. I keep mine on. It's the point of having a cell phone.
I presume it's just like a computer and only the service stays awake for these such things.
I hope so.

could be helpful though mostly i just stick my phone in airplane mode instead of turning it off.

well, in this video the guy clearly selects 'shut down.' I mean i'm still not convinced it's completely shutting down, but it sure looks like it

in that case its probably more of a standby where it loads the os into the ram. that would explain why it would boot slower after you pop the battery. however don't think most people swap batteries on a daily basis.

it MUST have decent battery life. hopefully at 18 hours given the proccesor is underclocked. though the second you stick cmod on it, batt life is probably going to drop significantly.

[Q] Battery drain

Hi Android users, i've a question - how about battery draining in normal using of touch pro? I mean using wifi about 10-15min a day, few calls and sms. It's possible to get standtime as long as Winmo(3 days)?
And how about charging - is it good for my battery to charge in Android?

Your battery should charge just fine in Android, but I wouldn't run this 100% of the time.
For one, if you play around with Android a lot, it's going to drain your battery. Talk to people with native Android devices, they don't get 3 days standby... I know someone got ~36hrs, but that was with almost 100% standby (sleep). Wifi is going to slaughter your battery, no matter how you slice it...
This isn't meant to replace WinMo! At least not at this stage in the development... Even if we do get to that point eventually, I doubt the battery life is going to be like WinMo - Android does a lot more than WinMo, and this drains you battery The joys of having a more functional OS.

thanks for answers
My sister LG Optimus (gt540) got standby time 3-4days, but I think reason is battery - 1500mAh Biggest I've ever seen (capacity ard real size)
http://www.lg-optimus.com/

Yep, but what a price :-(
I really like android, but before something like harder sleep+ignore apps idiocy will be inserted inside kernel, until that is android cool thing to play with it (on Raphael100, many ports..), but its worts when u need to be online (GSM, data [3g/wifi/anything else]) for longer time then day (with some data transfers).
Ill be really happy droid user again, when battery drain will be solved. But right now, ill prefer slower system, but usable for much longer time then droid (with using ssh, sync, etc.)

I wish we could get some decent battery life out of this. I'd just need enough to get through a day..8-10 hours would be OK...I'm using a rooted Nook Color for serious Androiding and an EnergyROM WinMo build on my TP.

Some report 8 hours, no idea how as my at&t fuze gets about 4 hours tops... but that was with gingerbread alpha2 and updated kernel package.

is it possible: Battery saving custom rom

is there anyone who can do this . android style??

the battery saving options currently present in wp7 mango are far superior to anything Android can offer.

What is there to do to save battery? Nothing runs in the background. All bloatware can be uninstalled the second you power on the phone for the first time. I don't see how you can get any more efficient than what Microsoft has tried to do in Mango, or by allowing them to continue optimizing it themselves.

Android has (or allows apps) that can do handy stuff like underclock the processor, turn on/off various services based on your location or time of day, and so on. That'd be nice

Battery saver in Mango already does that. As far as I can tell, it does:

- Disables all push data communications and sets mail check time to 30 minutes (for gsm)
- Disables background processes and tweaks kernel for less consumption
- Underclocks the processor ? (not sure about this one)
In this mode, it's superior to any other Android power saving mode I've seen. And you already have it so what exactly are you looking for?

underclock , radios on demand, ect

I'm pretty sure the OS by default under-clocks the CPU where it can.
The only thing I can think of that you could do further is turn the auto screen brightness off, and then turn the screen to the lowest brightness.

i'm curious what versions of wp7 and ios you're comparing to what versions android, and on what devices ?
also, what are the runtimes of these devices ?
specifics might clear the air.
I only have 4 devices to compare myself, g1 @ 32 days without a charge.. g2 with 14 days no charge... nexus 23 days no charge... hd7 with 3 days no charge.
what do you have ?

That's on my wishlist too.
I knew I forgot something besides what I've already mentioned
- Screen timeout to 10s
Speaking of battery consumption, one day I forgot to turn up the volume on my Focus. I use data connection daily (mail mostly and few minutes of browsing).
So, by muting the sound (vol 0 of 30), I get more battery at the end of the day with gsm data connection enabled (I receive about 30-40 mails per day). I'd say the difference is about 20-30%.
This could be something worth looking into for the MS folks...

Standby times are useless figures to compare.

Don't think it underclocks. I hit the battery saver mode pretty much every night.
But I agree with having Microsoft figure out best battery optimization.

Google Nexus 23 days without a charge..... u have gotta be kidding me. The only way it can do that is if you switch it off after charging, use a Windows Phone for 23 days and then boot it up on day 23

i dunno, if the phone can sit there powered on for a week, and still be usable for whatever purpose i'd say it's possible to compare efficiency assuming the battery is similar in mah rating.
otherwise, we'd have to run the same kernel, apps, libraries, and circuit board revision numbers... which isn't possible.
still, open to suggestions and eric1234 to clarify.

i guess it would be called 'idling', but it's powered on, with wifi turned on, checking 1 email account once an hour. i don't have a sim card in it currently. it's just a glorified hd camera/phone/thing for motorcycling currently. and trying new UI's/roms. the g2 slaps it around like a red headed step son. no offense, red headed step children in the room.
