Reasonable battery life expectations after Rooting

So sorry for adding to the battery life threads, but I'm pretty frustrated.
I've seen people posting screen shots with 18 hours uptime, 7 hours wake time and 50% battery on custom roms. I've seen people getting about 24 hours on a single charge.
I've had my evo 2 weeks now, and I've tried about 3 different ROMS and 4 or 5 different Kernels all of which promised LONG battery life. I'm currently running BakedSnack 1.7 with Kernel #5. My phone has been on 10 hours, 2 hours of wake time and it has only 35% left. Couple of short phone calls, 10 mins Pandora and a bit of browsing and texting here and there. I was expecting more after rooting, yet it seems almost the same as it was before I rooted.
Am I expecting too much ?
I've gone through the full discharge/recharge cycle about 4 times so far. Bad battery perhaps ?

will the phone charge get you through a day say 10 hour work day ( includes travel time )
imho your expecting to much with 10 hours in to your charge and still have 35% left is pretty damn good imho
Baked Snacks is a great rom ! its no the battery check your TWS

Depends what you are doing, some things (3d games, flash) will drain the battery faster than others.
If you are at 10 hours and 2 hours awake with 35% left, thats not too bad. You should end up around 16-17 hours with 4 hours of awake time.
If you are talking on the phone, that will drain your battery the fastest.
Make sure you completely condition your battery as well (as many posts show)

It will make it through but usually by 5pm its around 30%. I almost have to make an effort to use it sparingly though. I really like the Baked Snack Rom, its very slick probably the best I've had so far. TWS was 3% today.

I haven't even gotten into playing games or watching video on it yet to be honest and my phone calls are usually short.

30% by 5 stop please be happy with that lol

Have you tried SetCPU? I have stock rooted with SetCPU (Perflock Disabler ftw) and without a signal 13-25% of the time (meaning the phone is searching for a signal), I end a 10-12 hour work day with about 45-50% left. Underclocking to 250 while the screen off has helped a lot.

This seems to be a common concern. first please remember to take everything with a grain of salt when it comes to people reporting there battery times. There are just to many factors to say ok if you use this rom and this kernel you will get 20 hours of battery life. Also many of the people reporting battery life exaggerate. sure they may ahve gotten 50 hours between charges on stock battery... but they surely didn't have moderate use ... or any real use during that no matter what they claim.
from another post it seems the majority of people in that post (with everything tweaked calibrated and set up) were getting roughly 13-18 hours of battery life out of there phone with normal use. normal being defined by actually using your phone as a phone as well as using its other capabilities. So my feeling if you are a moderate user you should expect to fall into this area as a goal. Things to help would include setCPU, making sure you turn off data when you shut off screen (or getting a program to do so for you - juicedefender) and making sure you calibrate your battery and battery stats of your phone.
it seems like you are getting close to this range however you are having to watch your use to do so. as others have said the first thing i would do is get setCPU and set up a battery saving profile. read through some of the battery threads if you havent and look for setting changes that wont impact you tremendously but will help save battery (for example if you dont use landscape mode a lot you can turn off autorotation and save some battery). If you are using froyo and are running a task killer uninstall it since it doesnt work any way. While most settings will make a small impact together they should help get you to where you can use your phone moderately through out the day with out worries.

Don't get me wrong here, the thread wasn't about me complaining, more about setting my expectations.
2 Years ago I had the first Touch Pro which would be dead by 3pm regardless of usage. At one point I had 4 batteries. I got the Touch Pro 2 a year later and it could go 2-3 days on single charge with normal usage. It was like night and day.
Granted this is a much more powerful device than either of those, but I feel like I've taken a step backwards with the battery situation.

I tried out SetCPU but the phone was slugglish for me at times and once or twice I had to reboot.
I'm probably just gonna grab an extra battery and a desktop charger so I can charge one battery while the other is in use.

Thanks alot for those tips, I'll give SetCPU another go.
I haven't tried out Juice Defender but I'll look into that as well. Turning off Data when the screen is off might be just the thing I need!

Battery Life

In the interest of branching out of the main thread, I thought I'd start a thread regarding battery life- how many hours are you guys getting? For those who have somewhat decent battery life, what tweaks/settings are you using?
I went and disabled background data syncing hoping this would at least help improve battery life only to find that even idle (with no real use at all), this thing eats battery like there is no tomorrow.
I think with super light usage the most I've gotten is about 4-5 hours. There HAS to be a way to improve on this. I can never walk around without my charger in my bag- that is just crazy.
So any ideas or suggestions would be great! (By the way, I'm running Dexter's latest rom on top of eLocity's official firmware update).

I'm posting 4 hours 54 minute uptime right now with a quick 10 minute game of fruit slice, light to moderate web browsing, and moderate to heavy instant messaging. I have 29% battery left.
I generally set my apps to sync no more frequently than 30 minutes at the least. I turn the screen off when I walk away to do something. Other than that the tablet stays running on my couch side all day.
I have also seen it go for days on standby mode without going dead. I'm happy with the battery life. My Archos isn't much better, and is much less powerful of a device.
I'm also on ElociMod (which is based off the newest firmware... )

cant get more than 4 hours no matter what i do. running dexter's modc

We might be able to help the battery life using some clever tricks with SetCPU. I know it helped on my Pandigital Novel, and 2/3 on that device was used to power the screen, as opposed to ~1/3 for the processor. I'm gonna guess it might be the complete opposite of that on the A7.

It doesn't... it will FC.
CPU Tuner installs and runs. It shows a min of 260 MHz and a max of 1000 MHz, and it has profiles based on battery charge. I just installed it, so I don't know what to expect.

I wanted to resurrect this thread and post my experience with A7 battery life.
I am running Dexter 1.2, brightness at 35%, WiFi always on, Bluetooth mostly off, screen timeout at 2 minutes. Syncing three mail accounts, weather and Google calendar. Limited or no background syncing of other apps.
My typical day with the device consists of;
a full charge in the morning
3 to 4 hours of standby time
30-45 minutes of web use
another 3 to 4 hours of standby
3 to 4 hours of heavy web, texting, reading, and games
I place the A7 back on the charger at night and it usually has about 20%-25% charge left.
I figure I am getting about 4-5 hours of use and close to 8 hours of standby each day fairly easily.
This battery life is very comparable to my Droid 2 Global.

The ipad battery has more than 4 times the capacity of the A7, but only twice the run time.

Tips or What is in your opinion the best rom for battery life for the HD2?

I have searched around the forum but cant find any recent discussions on what is the best HD2 rom, i recently used CoreDroidGBX and i find the battery life to be pretty good on that (Lasts me till end of day with light use (Light use being screen on about 2-3 hours out of that day) End of day being 7:00 Unplugged Low bat around 5-6:00) But i see about 300-500 mA useage when im actually doing anything on my phone(But just like 2-3mA when its off and i disable data)
So i keep experimenting with different roms and i am wondering what you guys have experienced the best battery life with on your HD2's.
Also i have to manually toggle off data, is there a app to auto do it, like automatically whenever the screen is turned off? I had my phone on battery nearly 24hours (Although i was on my laptop and only used it for like 20 mins of phone calls and a few texts) but still a real full day was awesome

Coredroidgbx? There is a Coredroid series by Sergio and a hyperdroidgbx by Pongster. Both get rave reviews for battery. I run hyperdroid and I get 18 hours of normal use no problem. If you consider watching YouTube and flash video all day normal there is no rom that will last doing that.
Do you prefer a sense or a non sense build? GB or Froyo? CM7 or ASOP?

I would say u need to check some nand built on your own as different phone respond differently to rom built. hyperdroidgbx and rafroid hd 4 are good option to move ahead and check

+1 agree.
Thoese are my favorites too.
Sent from my Desire HD using XDA App

tried using CoreDroidGBX before also..
smooth... but battery is almost the same as other builds..

In my opinion the best battery life was in unofficial nightly CM7 by charsingh (1-3mA in standby). But due to some issues i had to switch to Typhoon CM, battery drain is notably higher (6-10mA standby) but for me it is the best ROM ever.
I think that the functionality of the ROM is litle bit more important than small diferences in battery drain.

Motoman234's Moto-MyTouch4G v3.3
Nand build and the best I've tried so far. I can get 2 days with light use (text and moderate calls) and a full day with fairly heavy use ie: web for 1-3 hrs and 1-2 hrs of various games along with calls and texting. I call my family on the east coast frequently and a 2 1/2 hour call is not unusual, loose maybe 20 to 25percent on the call depending on my signal. Great rom, a chef that responds and helps, again nand build. totally functional for me no issues flashed 4 different phones to it so far! .
I as a rule, leave wifi on always and use bluetooth, location, and background data only as needed. Blue tooth and background data will suck the juice right out! Still, if I forget and leave those on I can still get a full 10 hr day out of a single charge, provided i dont spend hrs surfing.

+1 for Cyanogen Mod 7. I tried a lot of DesHD builds but CM7 has the longest battery life by far for me. One charge lasts me about two days with light use. With all DesHD builds i never made it past 24 hours. Usually even less than that.
Furthermore CM7 is just beautiful, especially with cyanbreadX

i'm on rafdroid 4.0 and unplugged this morning at 8 am and the time now is 5:30 and i'm at 60% with moderate use and wifi off.
i will say though that if i play bubble blast 2 that thing sucks the battery like nothing and i'm not sure why. it's amost 1% battery per min i can feel the phone get hot from use.

Running cm7 unoficcial right now and seem to be getting good batter life, but I have seen it actually use 700mA (srsly) when just charging ..
But can idle forever. But lost 15% in an hour during lunch...

I just put HyperDroidGBXv7 on my phone a couple days ago and its been great on battery life so far. I unplugged my phone about a 12hrs ago and its at 74%, averaging about 3-4ma on standby. No classes today, so I've only used it lightly today for some quick wifi browsing, short gaming (Angry Birds), and about 30 texts.

Ok been trying cm7 and for some reason when actually using my phone I seem to get a steady 535mA battery useage, any suggestions on fixing this?

Anybody know why my actually using my phone usage is so darn high? I just flashed to the stock rom, reinstalled magldr + Clockwork and im about to flash android again.
Doubt that will help but i need battery life..

Over 24 hours on a single charge!! Awsome battery life!

I just wanted to share my battery life results of my NS with the community. I was able to get over 24 hours of battery life on a single charge. What amazes me more than that, is the fact that my battery was only at 72% when I took it off the charger. Much to my surprise the battery lasted me for the next 24 hours before it dropped to 16% and I decided I needed to charge it before going out this evening.
My configuration:
Rom: NS Collab 1.0.17
Kernel: Netarchy 1.3.0.2-CFS
Screen Brightness: Auto
GPS: On
Wifi Sleep Policy: Never Sleep
Email: Sync every hour
Facebook: Sync every 4 hours
Clock Speed: No special governors enabled
Most of the time I was connected to a WIFI network
Hope this may help those that have been having problems getting optimum battery life on their NS.

not bad i guess, i've gotten over 48 hours

Yup, awesome battery life with CM7 as well.

Yeah SI_NZ pics don't show any usage of the phone. Mine I talked for about 2.5 hours and was using facebook a decent amount. I also did web browsing, some videos for a little while, and I did a couple of video recordings of my son. Overall I used my phone a pretty decent amount during this time period, hence why I was so impressed. The same type of use on my EVO would have resulted in me having to put the phone on a charger before halfway through the day.

Darn... I'm stuck between the Nexus S and the HTC Desire HD, but the battery life on this phone must rock.
But how is battery life on a STOCK OS? I'm not much to root.

That seems to be a battery killer

I've found a few battery killers, maybe we should make a list and make it sticky. My phone easily lasts like 36 hours with normal use, which include a little gaming and lots of surfing, texting and calling. The apps i have found to drain the battery so far is:
Latitude activated in google maps. This is insane, latitude makes my phone go dead in like 8 hours !!!
a media player that i can't remember the name on :/

The Desire HD kinda sucks for battery life and I found it was too big/bulky feeling. It wasn't as fast as the Nexus S in everyday use either...the Nexus S is quite quick.

I'm on stock 2.3.3 out of the box and battery life is very good, better than I expected. I don't have too many specifics yet since I've only had it a few days. But so far it's impressed me again today with over 13h 30m 43s, with 44% display use, and 72% battery left. Perhaps I'll comment on the weekend after I calm down a bit and use it over a more typical day. But as it stands so far, I expect to get 1 day heavy usage, 2 days on daily typical usage, and 3-4 days when using the phone very little (like while camping/hiking).

Well 8 hours is quite good since it runs the GPS constantly and updates your location on the Latitude site. I ran other GPS apps on my Desire and typical times were ~4 hours before the first battery low warning. I haven't had a chance to really test the GPS properly, but initial use looks good.

2 days is pretty good. but you barely ever had the screen on. I can normally get 20 hours which lasts me the whole day, so I'm fine with charging every night.

I'm on stock 2.3.3 too. Typically I get about 35-40hrs.
WiFi: Off.
BT: Off.
GPS: Off.
Email/Calendar Sync: 1 hour.
Facebook: Off.
No fancy widgets though, just the stock clock and stock calendar. No task killers either.
If I game for about 2hrs during my daily commute, the battery lasts just long enough from 6am to about 11pm.

Forgot to mention how the phone is setup:
WiFi is off most of the time (I have 6gig data plan)
BT is off as I don't use an earpiece
GPS is always enabled (I'm a geocacher)
Gmail is set to manual sync (work is too busy for personal email)
Facebook/twitter/whatever are all disabled/not installed
News widget is set to update every 12 hours
I use a Live Wallpaper, Beautiful Widgets with animations, and I'ver never used a task killer as they're not needed.

Don't know where I have read that, or if it's just an impression. But I think that wifi connection consumes less battery juice than 3G connection. And push-Gmail doesn't increment battery usage.

I came from a blackberry (actually I still use the blackberry) and I was initially annoyed by the quick battery drain. But after seeing my friends with iPhones needing to bring chargers with them everywhere just to use whatsapp and gchat constantly, I was really glad I got the nexus s. I recently went on a road trip where I used the gps constantly to drive 4 hours out to the destination, used the phone there to whatsapp and call my friends, used the internet to look up restaurants, and then used the GPS to drive 2 hours back to our hotel and it lasted me the whole day. I'm stock everything with 2.3.3. I love this phone.

I managed to get over 48 hours on a single charge.
Thats with around 7-10 short phone calls per day.
Some whatsapp/sms
a few minutes of angry birds here and there
and some web browsing over wifi.
My WiFi is always on and set to never sleep.
sync is off.
GPS off
BT off.
My data is also usually off, since my work data plan is rather small.
Also i have simi clock running that updates the weather every 3 hours when WiFi is connected (which is most of the time).
I am on stock 2.3.3, unrooted.
after 3 days I had around 25% before I connected it to the charger.

The battery on nexus s is great, much more better than my old SE X10.

Could you please all tell whether you are on 9020 or 9023? I heard average battery results were not so positive with 9023 sclcd. Here I can only acquire 9023, and I have been reluctant to buy so far as people don't seem to reach quite the same autonomy as the samoled nexus owners.... Thanks!

How to get 36 hours on 1 charge

Alright, so I'm not a very heavy user on the phone but I've started getting 36 hours of use on my phone. I was blown the hell away! I usually would get a Max of up to 25 or 26 hours or so before this. Even then a full 10 hours extra is magnificent!
Here's what I've got going on:
Running MIUI 2.3.23 ROM with Bulletproof Add On pack
Using Tiamat 1.1.5 kernel
Juice Defender Plus on Advanced mode
Recaibrated my batter with Battery Callibrator app
Overclocking at 1039 MHz and underclocking at 184 mhz using SetCPU
After calibrating my battery I let the battery run out completely a couple of times and voila!
I took a screenshot of my usage statistics but I can't find the damn thing now. I guess you're just got to trust me on this. This was definitely worth sharing.
All the best!

How many hours of screen on time did you have at the end of that charge? The longest battery life i've ever had for my phone was actually 3 days and 3 hours with 5 hours of screen on time. I'm a light to moderate user and i achieved that result with CM7.2 RC1 without any tweaks.
I really like the look of MIUI but i don't find it to be as fast as it really should be. I get frustrated by the scrolling lag that is present in the settings menu and the fact that video playback is much slower in comparison to other ROMs. Web pages were also always SO much more laggy in MIUI for me than on Sense or AOSP based ROMs. That's my personal experience, i think i've just about given up on MIUI and Sense based ROMs. I haven't touched either of those for a while now.

I get 36 hours normally with the stock Sense 2.1 ROM and Unity V10 kernel. Overclocked to 1Ghz with the standard governor.
I use it quite lightly though, 10 to 20 SMS, bit of internet / Facebook and 30 mins FM radio in the morning. Also accounts sync automatically, mail picked up every hour, data always on. That was with the stock battery, with the Anker 1600 mah I get to 36 hours with about 30% to spare!
On a side note, underclocking below 245Mhz has been know to cause problems. Standby of Death (or Sleep of Death), and possibly dropped SMS etc.

How many hours of screen on time did you have at the end of that charge? The longest battery life i've ever had for my phone was actually 3 days and 3 hours with 5 hours of screen on time. I'm a light to moderate user and i achieved that result with CM7.2 RC1 without any tweaks.
I really like the look of MIUI but i don't find it to be as fast as it really should be. I get frustrated by the scrolling lag that is present in the settings menu and the fact that video playback is much slower in comparison to other ROMs. Web pages were also always SO much more laggy in MIUI for me than on Sense or AOSP based ROMs. That's my personal experience, i think i've just about given up on MIUI and Sense based ROMs. I haven't touched either of those for a while now.

I'm not sure how much screen on time I had. I'll give it a check next time I'm monitoring my performance.
Sense UI has been a pain for me from the moment I started. I tried CM 7 but it had a bug where it wouldn't vibrate when I got a message unless it was in silent mode. Since I SMS quite a bit, it was quite annoying. I tried a couple of Virtuous ROMs too but they were glacial in their speed. Couldn't stand the lag.
I find MIUI to be the perfect balance between features, UI and speed. It might be a tad laggy in some places, but on the whole, it looks great, works great and doesn't give me problems in the parts I use the most. It doesn't seem quite as laggy with me as you seem to describe it. But anyhoo, for the first time since I bought my DZ, I feel like I have a good phone that I can rely on.
Thanks for your comments, man.

I get 36 hours normally with the stock Sense 2.1 ROM and Unity V10 kernel. Overclocked to 1Ghz with the standard governor.
I use it quite lightly though, 10 to 20 SMS, bit of internet / Facebook and 30 mins FM radio in the morning. Also accounts sync automatically, mail picked up every hour, data always on. That was with the stock battery, with the Anker 1600 mah I get to 36 hours with about 30% to spare!
On a side note, underclocking below 245Mhz has been know to cause problems. Standby of Death, and possibly dropped SMS etc.

WOw! Really? Stock giving 36 hours! That's pretty sweet man. Never happened to me.
And thanks for the advice on the underclocking. Maybe I should up it a notch, just in case.

Go for it bro! And let me know if it works for you.
Right now, I've already hit 33.5 hours and have just hit 15% battery. And this is including a few games of Angry Birds. woohoo!

After calibrating my battery I let the battery run out completely a couple of times and voila!

Letting the battery drain to shutdown is not a good idea. Not good for long term life of Li ion batteries. Also, its unlikely, but possible that draining to shutdown will render the battery unable to take a charge. Fail safes on the device and battery are supposed to prevent this in theory, but in reality they don't always work. Several reports on this device of people that drained to shutdown, and then couldn't charge their battery.
The battery meter is not accurate enough to necessitate draining to zero. Just drain to 10 or even 20%, charge to full, repeat a couple times. No value added whatsoever to draining to shutdown.
I have easily gotten 48 hours+ with light usage on various ROMs, including ILWT and Virtuous Unity (which is Sense 3, and claimed by some to be a "battery hog"). This is with Bluetooth and WiFi always on, and no special battery calibration or battery saving apps.. So many things affect battery life. But my personal hunch is that the ROM, clocking, radio, and data reception in your area (and of course usage) have more to do with battery life than other factors. And with radio and reception being the really big drivers.

That's definitely very helpful. I've always heard that rechargeable batteries are supposed to be drained completely and charged at least periodically to extend its life. Your proposition is contrary to this belief but then, I don't know that much about the battery and those aspects of the device itself to be able to refute what you're saying. Best to be on the safe side though.
Current record for my battery is 42 hours as of today. I'm pretty thrilled. My device was giving at least 10-15 hours less before I made these customisations. So I feel it probably has helped. However, there are a lot of factors at play, as you said.
Thanks for the response!

There are various types of rechargeable batteries with very different behaviors. What you mention is known as battery conditioning, where you periodically drain to (nearly) empty and charge to full, and is recommended for older type NiCd (nickel cadmium) batteries. This is to avoid "memory effect" where the battery will remember how much was discharged in past cycles, and not deliver any more than demanded before. Kind of a "use it or lose it" principle.
Lithium (Li) ion cells (the type on most smartphones) do not suffer from memory effect. And full discharge cycles actually hurt the long term life of the battery. Charging frequently is actually the best for this type of bettery. But a couple nearly full cycles are needed to properly calibrate the battery meter on the phone.
