Battery Life Vogue Android

So, I recently got a vogue and immediately put android cupcake on it. (great work devs btw )
So here's the problem, I cant get through the day 7 am - 12 am with light to moderate use without needing to charge.
I would like to keep 3g/background data on during this time.
Has anyone had any success having their vogue-androids last this long?
Are there any advanced power managers that allow you to change the backlight quickly and easily or allow you to turn data off during certain times? (like data off for a 1/2 hour and then data on for 1/2 hour)
Thanks,
Kevin

There's an app called "Locale" which is apparently awesome, but I haven't tried it myself. It changes settings based on your GPS location, but I'm not too sure about time of day. You may want to check that out.
As for the battery lasting that long, I dunno... I don't think I'd fall into the "light usage" category. My battery typically lasts from about 7:30am till 9 or 10pm though... I'm not too sure, I usually plug it in when I get home from work around 6.

That would need more battery, since it would need GPS.
We don't have network-based GPS yet.

I have had the same problems with battery life on my vogue even with light usage. Also I don't believe CDMA has the same issues with 3g causing higher battery usage like gsm does. I have tried widgets to quickly toggle the backlight and gps function but only saw minimal improvement. Not sure if the increased battery usage is just a fact of android or if there remain porting/performance issues still to blame.

i've got my background data set to off and i keep gps and stuff off unless i need it and i've got my email set to update every hour and i found this actually gives me better battery life than when running windows so i just went and bought an extended battery off ebay and hopefully it'll get through a complete workday(10 hrs) where as right now i'm getting between 6 and 8 depending on how much I use it.

My battery used to drain pretty rapidly.. 7am - 2pm... but now it lasts from about 7am - 6pm. I think theres a certain amount that the battery can condition itself. I've tried discharging and charging and I do believe that its helped.
Do you guys notice that battery readings are not accurate though? Apparently it has something to do with the temp. sensor in the battery not being correctly configured. For example, if my battery is at 20% and I plug it in the charge, it'll jump to 40% in a matter of 10 mins.

well that's for my aol email gmail will not be affected i left auto-sync on and from what i could see it still auto-syncs without background data on you could uncheck that but then you'd have to manually update yourself

i too am having pretty bad battery life even when i don't use my phone. why would the battery drain so fast when its sleeping? would that togga app help at all with the latest cupcake build?

Togga has been replaced in Cupcake by Modem. They do the same thing, essentially. If you want to turn off your data connection, open Modem and click Disconnect.
Also, in your default.txt make sure the pm.sleep_mode setting is set to 0 for best power saving.
Lastly, update all your files to the latest. The newest rootfs.img is supposed to bring more power-saving functionality. I just installed it this morning, so I can't comment on it yet.

yeah i just updated all of my files, ill check my text though.

i checked my text and it is set to 0 already! not a good thing when it only takes 5 hours to drain 50% of my battery life. i hope this can be fixed in future builds, i may have to go back to winmo for the time being because i need my phone for work.
i really love android though!

Do you have "Use Background Data" unchecked under Settings > Data synchronization? This makes a huge difference. If you have unchecked already, I don't know what to tell you.

with the previous rootfs (just before the new one today 2009-08-04) I've been getting 10 hours with moderate usage, backround data enabled, contacts and gmail auto syncing and locale set to turn my ringer off based on location (btw, I do beleive we have agps working now). Upgrading to the newest kernel and rootfs with more improvement to see if I can get a full day as I am awefully close now.
oh, and I also have a weather widget updating every hour, pretty good battery imo.
EDIT: Tip for battery life, I have my default screen brightness set pretty low, about 30%, as this is fine for most indoor conditions. I use an app called fastbright placed conveniently on my home screen to immediately turn my screen to 100% with the click of an icon when I am outdoors. I also use locale to turn the screen all the way down to 10% when the battery is less than 10%. Both are recommended apps.

I think I was getting much better battery life before introduction of rootfs, like on the order of 4-5 hours more (running hero themed ion). Anyone else have this experience, or is it just me?

Actually yeah, I tried the latest initrd and rootfs today, but it seems like it's a bit lower than it usually is this time of day. I think the first implementation of rootfs was better than this latest over the non-rootfs versions, though. Maybe I just used it more. I kept all the same settings and usage for the day was typical.

Best option is to buy the Extended Battery from DealExtreme for $8.. search for HTC Touch S1 .. the back cover doesn't fit properly but you can always get a one that fits from ebay..
this battery lasts me thru out the day even with heavy usage.. and for $8 u can't go wrong

Today I didn't touch my phone for the first 4-5 hours of my day after charging overnight, and was down to sixty-something percent. I know that on older initrds I was doing much better than this, at least 80% at noon with no usage.
I'm wondering if optimizing memory with the new rootfs stuff has been a trade-off to poorer battery life. Since I'm using mssmison's hero themed ion which is screaming fast, I haven't noticed a difference with the root stuff and think I'm going to try switching back.
I'm switching back to the 7-30-09 initrd.gz, because that's the last one I know my battery was doing much better with and will post back after running it tomorrow.

My issue with battery life is that my phone doesn't seem to know how much battery it has left. It will be on 60 percent, I'll plug it in and 5 minutes later its fully charged.
Or after it comes off the charger overnight, it will go down to 60-50 almost immediately but stay there all day while at work with light usage. I also hate that it doesn't know when its full, I hate to overcharge the batter. So many opinions on if it damages it or not.

People complaining about battery life

I honestly want to know what you expect.
I woke up at 4AM this morning, and it's not 8PM, and my battery is on 61%. I've done e-mailing, made phone calls, received phone calls, texted, surfed the web a bit waiting for a buddy to meet me at the mall, and Shazamed a couple of songs that came on the radio in the car.
How long do you expect a battery that'll fit in the HD2's slim form to power its extremely demanding hardware?

All expect is a functional and practical device.
I bought this as a work phone. It isn't always practical to be carrying around a phone charger.
"Before we start the meeting, do you mind if I plug my phone into your wall socket?"
Having to plan around charging points on a long work day on the move defeats the point of a mobile phone.

I understand what you're saying about expecting too much, but perhaps phone companies should consider not making such poweful phones until there is a battery powerful enough to support them. It's all well and good having such great technology, but if you can't use it how you want/should what's the point? Just a thought.
Personally the poor battery life doesn't bother me too much, but then I'm not out and about all day.

With the latest radio and an efficient ROM, all that is unnecessary (even with the stock rom and latest radio I bet).
I usually charge it overnight, but forgot to do it last night.
I removed the charging cable yesterday at 8AM, made about 20-25 minutes worth of phone calls, 20 minutes surfing on internet + a few e-mails, around a dozen picture, 10 minutes GPS (iGO8) and messing around with the phone a bit from time to time.
It's now 10AM, so 26 hours later, and the battery is still at 75% (haven't put it on a charger at all, not even in the car while using the GPS).
I wouldn't really call that "having to plan around charging points".
I agree that during a busy work day, you could have more phone calls, but still, you should have plenty battery left (especially if you don't forget to charge it overnight like I did )

Just wanted to share with CHIP how I get around a busy work schedule with the phone.
The key thing is the USB sync/charge cable, when at my desk I sometimes plug the phone into the notebook dock via USB for juice, and it doesn't hurt that it's also syncing with the laptop.
On the move, I've got a USB socket adapter thingamajig for my car's cigarette lighter socket, so if the phone is low, it gets plugged in.
Furthermore if I get the chance to plug the laptop in like in a long meeting, the phone also gets plugged into the laptop via USB for more charging goodness.
It will probably kill the battery quicker this way, but it sure beats not being to use the phone at all, and besides, we did buy a phone that can have it's battery replaced easily right?
in my neck of the woods, you can get a third party USB sync/charge cable for about USD$9...

What would you class as an efficient ROM ?
I find the battery life on this phone abysmal .. To the point i switch off all wireless services except the one im using at the time to enable me to have any time on the phone at all .. Surfing the web on wifi with the other wireless services on i can practically watch the battery life decrease every few mins ..
Something is amiss .. I upgraded the radio to the 2.07.51.05 version but ended up going back to 2.06.50.04 as i found it to be better ..
Whats your profile for enabling wireless services, do you have 3G enabled all the time, Wifi, Bluetooth ?
Cheers

How much battery do you lose over night? On my phone it drops about 12-15% in 8 hours (radio off, flight mode). To me, it seems too much...

there is a problem with battery life,there are lots of problems with this phone..currently my opera browser stopped working,the sms is still not fixed..
the fact that you have no problem with your device does not mean it's the same for everyone..

It's definitely ROM and Radio dependant. The ROM I'm using at the moment is incredible. Comebined with the latest 2.07 radio and my battery lasts for ages.
I was only getting about 10 hours with very light use and push email on when I was on 1.48. Now I'm on a 1.66 based ROM and the battery last about 300% as long.
I'm currently on about 26 hours since last charge and still got 38% battery. That's with push email (peak times 7am til 11pm), lots of surfing, about 20 mins talking and some texts. Over night I lose about 1-2% max.
I'm telling you, with the latest software, this is a different phone. Also it seems like it sorts out the SMS bug too. Upgrading makes this phone everything I wanted it to be when I got it 3 months ago.

Interesting ... I have been using the 1.66 series also and battery is poor.. i need to keep track of proper usage to really see whats going on given i use no push email either .. Im wondering if it could be due to the fact location is on and also the radio is looking for 3g when im in a gprs only location, could all be contributing factors .. gprs data always seems to be connected too ..
Life was simpler with the iPhone (less fun though)

On the ROM I'm using in the Wireless settings there is an option called 3G - Change to GSM Mode. This drops the connection down to GSM if there isn't a good 3G signal. Also there is a setting in BsBTweaks called PowerSaving that I have turned on. This combined with the fact that the 2.07 Radio gives me about 1 bar better signal everywhere seems to have made this phone perfect for me. Maybe you should start experimenting with some battery saving tweaks like this?
I woulld definitely turn off all the auto download stuff like weather, stocks, time sync, twitter etc (except push mail). I mean how important is it that the weather is up to date 24 hrs a day when you probably only look at it once or twice a day. If you need it you can just press the update now button and within seconds you have it updated anyway.

Mine did behave reasonably well untill I started throwing apps and mods at it as fast as I could to get it to the point where I was happy with it. Lights out last night for me was at 01:30 with 94% charge,bluetooth off,gprs connected and trawling for e's avery 15mins..at 06:30 the battery was down to 41% with no programs showing active on task manager and thats after a tidy up last night with MemMaid as well. Guess who's going to be flashing his first new rom later this week ..

Yes, i have all auto download stuff off, weather just annoys me with all that moving clouds etc .. Twitter i refresh when i enter the app.
I have Change to GSM enabled. i am presuming this setting will continue to search for a 3g signal though .. Figured this used more power as the radio would be working harder no ?
I have power saving status enabled ..
The 2.07 radio for me i found really made the battery drain, notcibly so.. I moved back to 2.06 as recommended by the Miri page as i was using his rom at that time .. Not bothered to move back to 2.07 yet .. i may do in a day or so once i get a baseline to compare against.
The other night when i was on 2.07 i surfed the web for half an hour and listned to the engadget podcast for an hour, probably half of that with the screen off and i lost around 30-40% battery .. I blamed the 2.07 as i had better battery before i moved to that i thought..
I need to analyze this rom over the next day or so, i got the device 5 days ago and every day since i got it i have flashed one or more roms / radios so ive not really had a stable config to benchmark, what i do know is that i have the above settings enabled in all roms .. Ill be trying not to flash for the next couple of days to see whats what ..

Why do you need it scanning for emails every 15 mins while you're asleep. Why not change it to manaully download them in off peak hours (1am-6:30am) that way they'll still be waiting for you when you first wake up but not wasting battery checking while you're asleep.

On one of the other battery posts someone said that you need to give the battery a couple of discharge/charge cycles down to 1% with a new ROM/Radio in order for it to accurately be able to predict its charge loss. Don't know how much truth is in this but it might be better to stick with one for a couple of days at least before changing so you can get an accurate comparison.

Ok, yeah ill give it a couple of days to see whats what before i really damn this beast and have to buy the fat extendo battery with kickstand

The rom I found the most efficient is the one I'm using right now (XannyTech Pandora 1.1, though I've read that 1.3 is even better), and my radio is 2.06.51.07.
I have 3G/HSDPA enabled all the time checking for e-mail every 30 minutes, and the other services every hour (except during the night, where it's set to manual).
Wifi and Bluetooth are disabled unless I need them, though (I think that leaving them enabled would make a big difference for my battery life).
I usually surf the web using HSDPA instead of Wifi (since it's pretty fast here), unless I have to download bigger files
I'm not sure how much battery it uses overnight since I usually sync it and leave it charging (only forgot a few times) but I'm pretty sure it was under 5% last night.
Changing the radio and ROM really did make a huge change for me.
The same situation when I was on 1.48 stock + stock radio, my phone would probably be around 20-30% battery instead of 75% at 10AM this morning.
Btw, as an update, I've made about 10 mins of phone calls, and surfed the web over 3G for 10 minutes since this morning, and the battery is now at 68% (3:30PM), so it's been off the charger for 31H30 now.

I had the phone on in airplane mode, en route back from Brisbane (12 hour flight) and listened to music intermittently, and the battery wasn't drained that much. After another flight (2.75 hours) to Vancouver, the battery was still over 50%.
To be honest, I'm actually impressed with the battery life..

Thanks, at least this gives me some hope .. I usually would use 3g for my web surfing but on O2 uk carrier they have no 3g in my area, it will be like this until i get the HD2 unlocked and get on Vodafone, so for the moment im using wifi ..

battery life improvement?

hye,
I just bought a HTC leo which I really love.
but there is just one thing I'm concerned about, the battery life.
with my htc touch pro 2 I was able to use my phone 2 days before recharging but I can't do that with the htc HD2
IS THERE A WAY TO IMPROVE BATTERIE LIFE?
thanx

use less of your phone the hd2 drains the battery and is very good at that.
Or you buy another spare battery to switch with the exausted one when you're on the go, they're pretty cheap on ebay with a mains charger

only tips, would be turn all you're updates off, i.e, email, weather, twitter, stocks etc. screen brightness, not much else really, i get a full day out of my battery with everything turned on and full screen brightness so im happy

switch off 3G whenever there is no need for it, best is using a tool like wmlonglive to do this automatically. Will improve the battery live especially if signal strength is changing often between 2G and 3G

don't use windows live push mail, it will improve your battery dramatically
edward

my HD2 just takes 30 minutes to drop from 100% to 70 % .....
from the bottom of my heart , i want to say , htc fone ..... not good as they say ,
crap
battery drinker
just after some games , it hots ...............
will change other fone ,

I do not have a problem with the phone. it lasts me 2-3 days depending on where i am. thus depending on phone signal strength.
Further when you want to improve battery life look at the treads about that. there are so many with so many suggestions. quite a few have improved my battery dramatically. search and try.

@Felix
Are you using a Stock-ROM?
When yes, then install atleast BsB-Tweaks and activate the powersaving settings ... (the most cooked roms already have this settings)
It will bring some extra minutes/hours
My HD2 (fully loaded over night) is at 77% after 8 hours and some phone calls (ca. 30 minutes), sms and some gaming and surfing
@enchanter
yes, it drains the battery pretty good and yes its becoming hot when you play games or stuff ... but what is the problem with it?
We all knew this - before we bought a HD2

ha ha , Pliskinius has the coolest answer
" what is the problem with it?
We all knew this - before we bought a HD2 "
u right man ,

@ pliskinius: I don't know what a stock rom is... it is the rom who was installed when I bought it.
my battery lasts one day and a bit, so there is not really a big problem, but when you go somewhere and forget your charger...
@enchanter: I'm really pleased with my htc, its my 6 or so and they become nicer and nicer..

Try this fully drain the battery until the phone shuts down then take out the battery for two minutes,put the battery back in (DO NOT TURN ON THE PHONE) and charge until the green light comes on, take out the battery for another two minutes then put it back in and start up, this should improve battery life.
Also other factors affecting battery life are the Rom version,Radio and HSPL.

nice idea @nosh - will try it too ... maybe it brings some extra minutes
@Felix
you are using a stockrom (stockroms are the original ones, wich are installed when you pick up a new phone)
get this little tool http://forum.xda-developers.com/showthread.php?t=589305 and activate the energysaving feature (will improve the battery life)

@ nosh 10: I'll try that thanks, but I heard that fully draining your battery is not a good thing.
@ pliskinius: haha, yeah I know I don't know a lot about WM

Laurentius26 ROMs get an excellent battery life. I get 2 days without deactivating anything. And everything works perfectly and smoothly. I have the 2.10.50.26 radio ROM and the Laurentius26 GoldEdition V2.0 Spike™ WWE 21899. Can last up to 2.5 to 3 days by deactivating 3G. I download weather every 3 hours, tweets every 4 hours, e-mail every hour. Then I make phone calls about 15 minutes per day, sms 10 to 20, pictures about 10, surf with Opera about 30 minutes per day. Remember also to close all unused applications (for me the best task manager is the Touch X manager that is on Xperia X2, lets you choose between short click on the cross to minimize the app and long click on the cross to close the app).
Edit : It's now 15:50. Was 100 % yesterday evening by 22:00. Now it's 73 % left. But I only used my phone since that time to make a countdown for cooking at lunch time.

I'm currently in Japan, using phone on 3G, very little use, listen to some music daily (30 min) and play around an hour. I'm getting 3 days easily without a charge and could easiy stretch to 4 days.
Back in my country I disable 3G and use only 2g with auto updates on every 3 hours, no email push no twitter whatsoever, just weather updates. During the night the battery drains down by 15% and with normal usage I'd have to charge daily.
15% during the night with maybe 2 updates during the night and data connection disabling just after a few minutes shouldn't drain the battery by that much. Dunno, but I'm pointing my fingers towards 2g.
I'm no expert, actually I'm far from that, but could it be that 2g uses more power from the phone?
Without any usage at all, here in Japan, I hardly get a 10% battery drain in 24hrs compared to 15% during the night back in my country.

Maybe new comm chips Edge eats more than 3G as all the phones are now optimized for 3G, I wouldn't be surprised at all.
But one thing is sure : if you have bad 3G coverage or bad quality signal, it really drains your battery. Only way to avoid this : disable 3G and you phone will stop changing from Edge to 3G or HDPDA several times per minute.

I'm using WMLonglife, and I've set it to 3g only. Now I have no idea if here in Japan they have HSDPA or Edge or if the software is keeping the phone on 3g, but I haven't seen the phone changing from 3g even when the reception went down to 1 bar.
But i'm pretty impressed with the battery life at the moment. Pity i won't have the same battery life back home.

Battery life is extremely short

Hey guys, I've had the phone since Saturday and even though I've been through a few charge cycles my battery only lasts about 6-8 hours. Today I took the phone off the charger at 10:00 AM and it died on me at 5:45 PM. I only texted a few times and only did an hour or so of Slacker Radio. Seems a little low for what I'm doing with the phone.
I am on Kumar's classic 2.2 ROM with 2.11 radio.

A lot of things can drain the battery, 3g on in a no 3g area, weather updates, twitter , email updates ...
But If I was you I would try a diff radio ... I get a full day out of mine at this point a little more ...

I've tried 2.12 as well and the battery didn't improve.

Is your activesync checking as items come in? That's what drained mine terribly. Basically, it can be a ton of things that make your battery drain such as:
1. backlight
2. agps
3. certain programs
4. etc
You'd have to list a bunch of stuff on what you're doing to your phone

Can you turn activesync off? If so, how?
Also, any other tips to save battery life?

Definitely lower down the screen brightness to 20%, turn off Bluetooth and WiFi, don't let things like Twitter and your e-mail update so often.
Also using the internet/music/videos will drain quite a bit of power, especially if you use the internet while listening to music.

Yeah I mainly use internet radio while at work. Would using WiFi be easier on the battery than using 3G/H?

Yes, I've done it both ways and wifi most definitely draws less juice when streaming data than 3g (and when idle too, for that matter)

do you think it matters whether you install programs on your SD card or on the device?
i have CHT installed on the SD card and i can't make it 8 hrs on light usage.

I only have 3 apps installed so far, but it's on the device.
Also, is there a way to have the default wallpapers without animation? I'm sure that doesn't help the battery every time I unlock the phone either.

Yes. Try installing it on and running it from the phone instead, I'm sure you'll see at least a noticible difference.
Honestly, there's really not much of any reason to install apps on the SD card with this phone...there's more storage available than even most power users would ever come close to filling.

im in teh same boat. had it since march. on elegancia rom which people say is great for battery. on 2.12
now im in a bad service area in my basement often so i know sometimes thats the cause. but even at the gym 40 mins of internet radio dropped my battery almost 20 percent.
if i do nothing with the phone it usually drops 5 pct an hour 10 pct with moderate use but 20 easily if i do anything on the web over 3g or wifi. its awful
oh and i have lumos configured, i only have email connect every 2 hours and weather every 6. nothing else connects

Wow! your phone's battery usage sounds a little over the top. Might want to try using a different radio. 2.08 has given me the best signal/battery efficiency, but of course that varies from phone to phone.
Also, I bought a 2600 mAh battery so now I'm not afraid to use my phone. As long as you don't mind the extra bulk it adds to the back of the phone , I would suggest getting an extended battery to everyone complaining about how their battery dies too fast.

I will back up the statement that putting apps in main memory will save you battery ...
The less your phone has to access the SDcard the less power it uses.
A big thing is if you have any apps that run all the time that are on the SDcard , not only does it drain battery but will degrade the performance of the SDcard .

Anyone else have any ideas?

talked to tmo on webchat last night got em to send me a new battery
so if nothin helps at least il have two

I'm trying that method right now, we'll see what happens.

[Q] Battery Drain? And Opera memory problem?

Updated to the new TMO ROM (3.14 and the new radio too) a few days ago and I've been noticing that my battery is draining too quick for comfort. Maybe I'm just paranoid because it's a new ROM but does anyone else lose ~6-10% a hour (standby + occasional texting)? And when I go online (using Opera 10 with or without wifi) or make a phone call, it feels like ~30% per hour.
Am I expecting too much from the battery or is this not normal?
PS. I already did a hard reset a couple of times after flashing the new ROM + countless soft resets after reinstalling a few cabs (CHT, Duttys, CleanRAM, EndKey, and Opera 10).
Thanks!
PPS. While I'm here...sometimes when I close Opera 10 and run other programs and then try to reopen Opera I get this warning: ***Cannot open 'Opera10-armv4i' a critical component is either missing or cannot start because program memory is unavailable.*** Then it tells me to check task manager and close programs and start again. But I have no other programs running and I use CleanRAM and I still can't open Opera. The only way I can reopen it is via a soft reset...
Is that also common?

I'm at 44% battery and I've been using it moderately all day since 7AM... That's 12.5 hours... Not too bad for me.

Hey, I just got an HD2 [TMOUS] and I installed NRGZ28's Energy ROM for the phone. I am new to this forum, but I know the rules since i Have been residing mostly around the Developers forum and the Excalibur forum. in any case, I did a lot of research last night on how to get the best battery life. I AM using Sense [I know that eats battery], but I removed pretty much everything I can think of from the homescreen that uses data connection. I turned my E-Mail to Update only when I tell it to ... i removed the weather panel [heard it could use up more battery due to effects] ... removed the FB panel (i can just use the app) ... and the twitter panel... Then I did as other guides said and turned off the "My Location" feature. I also did some reg tweaks I had read do some real good for the battery, and so far I have yet to notice any difference than before I did all that.
My report is that I loose about the same as the OP ... roughly 10% per hour. I mean, okay, 10 hours of battery life is OKAY IF I WERE ACTIVELY USING THE PHONE. I lose 10% when just going through the phone, not running games or music, or viewing photos or videos. Just on Sense, going to the Settings panel alot , through the Start Menu, and the lockscreen occasionally.
First off: Is that normal? Is there are more energy efficient ROM? What can I do?
Secondly: I am aware of Extended Batteries, and I have researched some of these too ... I heard the 1600 mAh one that fits in the satandard casing actually doesn't do much ... then there is a 2400 mAh (?) which requires its own back-casing because it is larger. I got an extended battery along those lines for my Excalibur, and was satisfied with how it made it easier to hold ... but does the bulk make THIS phone look worse? It sort of worked for the appearance of the Exca, but I feel like on this phone it would just look like a giant tumor ... Any recommendations? Any good standard size, expanded life batteries?
Thank You so much [in advance]!

Your battery should be lasting longer than 10 hours. Mine lasts 12 or more hours with FB Data, Twitter Data, Push email and all of that with moderate usage. Mostly texts and emails, twitter and FB. Do you have your Automatically Adjust Backlight box checked and the other options checked under sounds & display in settings-->Backlight?

Indeed. My battery lasts at least 12 hours, most of the time 14ish hours before needing to be recharged. Haveing the system regulate the backlight is the single greatest thing you can do to conserve battery life, and alot of people have it tuned off for some crazy reason.

Hmm...I had read that I should turn off the backlight auto-control and install "AutoBacklightSteps" (or "AutoBacklight") ... That is what I have now at least ...
Right now I have brightness set to 20% [on battery], and higher on external power. Auto- is turned off. I use the app to change the backlight setting when I need to, although I often don't.
Now I don't personally use phones very very often. Seeing as I am in school, and one of the few kids who actually takes notes and doesn't text in class, I will use it for maybe 30 minutes at most [cumulatively] from 7AM to 3PM. Today, I used my phone as I think I normally would ....actually probably much less. In any case, it is now 10:33 here and I have 55% battery life. This is how I ran the phone for the day:
6AM : Took the phone off the charger [100%]
6AM -> 7:30AM : Phone left relatively un-touched. [98%]
7:30 AM -> 2:45 PM : the "Phone" [in comm manager] is off, in 'Airplane Mode' ... relatively low use [@ 2:45 -> 89%]
2:45 - 3:30 : I had 'Phone' on, received text messages I had gotten throughout the day, then turned it off [87% / 88% ... my memory is a bit fuzzy]
3:30 - Now : I generally had the 'phone' off, and I was in airplane mode. I intermittently turned it on.. I played some games, watched some moves [with Window Media Player] (I literally watched like 5 minutes of Transformers to show off to my friend haha, then I was done with that) Not much else...
All day the screen's brightness was at 20%. I used the LEDs for some flash photos, and the flashlight very rarely. I did take a couple of photos randomly thoughout the day ... but that was it. Right now, [after having the phone ON for about 30 min], my battery is at 55%.
I have to say that isn't too bad. Maybe the reader just wasn't that accurate yesterday, or I was doing a lot more than i though I was hehe [Could be file transfers and such]... In any case ... is this normal? I do expect to use the device more and more later on, I will text more and such [use Web sparingly as I know it eats battery] ... if I can manage to get though a day without losing power entirely I'll be happy haha.
Oh, and just some 'stats' : Today I placed 5 Phone Calls, received/sent 10 SMS, used internet for maybe 15 Minutes. That is basically it [since I know that probably affects seeing if battery consumption is normal].
PS: If you noticed I have the phone in Airplane mode a lot, it is because the signal for T-Mobile doesn't get into my school ... something about the dropped ceilings or just the architecture prevents the signal from entering, so I just generally leave it in airplane mode.
In any case, I would like to thank you guys a lot for already responding to my prior post
