[Q] Best Rom Desire S. Battery Wise!

What is the best ROM for Desire S in terms of battery.
I used virtuous unity 1.29.0 and it's battery backup was quite good then my original ROM.
But after updating to new virtuous unity 1.31.0 the battery backup goes quite bad.
Anyone know a good battery backup ROM for desire s?

Calibrate your battery, really works!
Instructions:
1. Turn your phone on and charge it for 8 hours our more
2. Deplug charger, turn your phone off And charger it fit one hour
3. Turn your phone on, wait 2 minutes,turn your phone off and charge it for one hour
4. Turn phone on and your battery life should be much better now

Don't forget to sacrifice a virgin and hire a shaman.
Cmon ppl! Li-Ion and Li-Poli batteries do not require forming (yeah its forming not formatting). Ni-Cd and Ni-MH were the types that required this.
In extreme situations (charging over 20hrs) you can even damage/reduce capacity of your phone's Li-Ion battery.

I'm saying that the type of the battery used in Desire S is not formable. Additionally in extreme situations you can damage it by overcharging it. This is more complicated, because it also depends on the type of charger, and charging hardware in the phone.
What DesisreS says looks exactly like forming process, hence my response.
What you (possibly) can do, is calibrate your device/os to properly read battery status and use it more efficiently. But this is done through some software tricks I don't know.

Our battery is smart.
Overcharging it won't do anything. It just cuts off the electricity when reaching 100%. Full voltage is around 4.2V. If you look at your voltage while charging, it's already at 4.2V at around 70%. I have no idea why it does that.
And at 0% it's not really empty. It still has around 3.5V. It gets dangerous at 3V where it won't be able to charge again.
Just clear your battery stats in recovery or use an app from the market and see what happens.
Read and search around the forum for more info.

You can use the app called battery calibration from the market for the calibration
Charge battery to 100% & run the app
This does not increase battery life but helps the OS read the battery more accurately & this needs to be done after installing a new ROM

Uhuh, this is what I mean. But lets go back to the original question, what are your experiences with different ROMs and battery life? I'm going to be Desire S user soon so I'm curious too.

LeeDroid ROM. Offers great battery life and very close to stock ROM. I got 1/2 day use on stock ROM with heavy use when I first got it, then put leedroid on, now I'm having 1 full day heavy use before I have to charge my phone (15%)
(Includes a lot of syncing, WiFi, web browsing, music,games etc the whole day)

@olyloh6696 i think you should also try the vu beta im impressed by it

i really hope the next version of miui for desire s will have better battery life, i think it's the best looking rom and i will definitely keep it when battery is improved!

OEM batteries will give you best performance than Non-OEM, higher value batteries. Your Stock 1350 mAH battery will definitely give better performance than 1500 mAH non OEM battery. The battery drain problem is in the root of Android 2.2 Froyo, Install Gingerbread if you want more backup

Using ur cell wisely also helps
Reduce your screen brightness and avoid vibration whenever possible
Also Live Wallpapers suck up lots of juice
Using the FIT moderately gives a decent 2 days battery backup (on a stock battery)
---------- Post added at 12:36 PM ---------- Previous post was at 12:11 PM ----------
And where do u source a 1500 mah battery for the FIT from ???

Upgrading your firmware or installing a custom rom may help with the battery problems. Also kill the apps running in background ,if not in use .

i bought one on ebay its pretty cheap, 4 $ witch isnt a lot so i will try it when i get it, will tell you if its good or not..

How about calibrate the battery? Does it really works???

calibrating only show correct stats, it has nothing with battery life

Use android software for calibration. Calibration helps to see the real level of the batery. It is a good thing to wipe batery stats when you reflash ----from cwm.

No, is better buy a new battery when the problems apears.

Download Batery calibrator from playstore it helps it restarts your batery stats rom will correctly read your batery data

it happens with high end phones like S2 also!
every smartphone has same problem, there is nothing you can do about it until hydrogen batteries becomes safer for house hold gadgets like cell phones
buy Motorola RAZR MAXX if you really need a decent battery life!

yea battery drain is natural
I think these batterys are limited to charge and it damages
Only way is to buy a new battery
but you can use battery saver apps in idle times

How to calibrate your battery

I have been seeing a pretty good amount of posts lately about how to properly calibrate your battery. This is a quick step by step guide on how to do so.
I will outline 2 ways to calibrate your battery.
The first way is using a free app from the android market (easiest IMO)
The second way is using CWM.
But first.... Some common questions.
Why would I need to calibrate my battery?
Anytime you flash a new rom it is recommended to calibrate your battery to optimize the battery life of your device.
You can calibrate your battery at anytime if you believe you should be getting better battery life.
How does it work?
When you calibrate your battery you are wiping your batterystats.bin. This allows for your operating system to create new battery stats that can drastically improve your battery life.
Using battery calibration app
First, install Battery Calibration by NéMa from the android market.
Once installed...
1. Charge your phone to 100%
2. Without unplugging your phone... open battery calibration
3. You will have to allow root permissions if first time using the app. Make sure the app says your phone is charged to 100% as well. Your voltage should be 4200mV or as close as possible.
4. Click on battery calibration in the middle of the screen.
5. Unplug your phone.
Now your battery stats are fully wiped. To fully create new clean stats follow the next steps.
6. Without charging your phone at all... let it die completely until it shuts off.
7. Plug your phone in and without a break let it charge to 100%
8. Unplug your phone
9. Let your phone die completely until it shuts off.
10. Fully charge your phone to 100% battery again.
11. Unplug your phone.
12. Let your phone die completely until it shuts off (last time)
13. Charge your phone back to 100% again.
CONGRATS! Your battery is fully calibrated!!
Note: it is recommended to do 4 full cycles to completely calibrate your battery but you should notice a difference after the first cycle.
USING CWM
1. Charge your phone to 100% full.
2. Reboot to CWM (recovery)
3. Scroll down using volume keys and choose advanced
4. Choose wipe battery stats
5. Reboot phone.
Now your battery stats are wiped. To fully create new clean battery stats follow steps 6 through 13 above.
As stated this is just a quick guide for reference for anyone having questions regarding calibrating your battery. If I have left anything out feel free to mention and I will add it in asap.

The second is from the Tab forum, but apparently our phones have the same MAX17042 fuel gauge chip which reads open circuit voltage to provide battery stats. As Vlad_z states, deleting the log file does not actually calibrate the battery, this is done automatically with the MAX17042 chip. The 2nd link does give instructions on how to reset / calibrate this chip without a jig.

I have definitely noticed a difference after using the battery calibration app as well as clearing battery stats through CWM.
I did try vlad_z calibration as well. I am still in the process of letting my battery die currently for a comparison. However it has been about 26 hours and I still have 37% battery left with moderate use.
I will be updating the OP to contain Vlad_z procedure as well

Nice post. I always just calibrate through cwm when I hit full charge. I never do three complete drains and recharges though. Usually one complete drain one complete charge and then use my phone as normal. Have you really noticed a difference doing four full cycles?
also it step 6. I've found if you power the phone back on after it dies it will truly kill the battery.
Still cool to get over 36 hours of use on this phone. Almost as good as my old dumb phone(which I sorely miss).

I have 5 batteries for this phone. 2 are 1500mAh and 3 are 1800mAh.
I assume I would have to recalibrate for each battery?

What do you need all that power for? Do you have five devices? I Would think you would calibrate based on which mah you are using since you are only deleting a file on your phone. I.e once for 1500 and only use those batteries.

Internal memory of the fuel gauge chip has room for two battery profiles, it cannot hold 5... so, if you are using all 5 then state of charge (soc) reported back to OS level would be pretty much inaccurate.
You can delete batterystats.bin all day long with cwm or apps - this is just as usefull as dancing with rainstick around your phone.
If you absolutely need multiple batteries then stick with same nominal 1500 or 1800. That way fg chip would report average value, granted your batteries should be the same age and health.

Posts like these are truly helpful, This should be sticked imho. I'm a complete noob to flashing, just performed my first two flashes last night, and it's a job trying to scour through these forums and read through all the posts trying to find the information you are looking for. I did it, and I'm very happy with the results. Damned if I was going to ask a question on these forums. you guys got me scared. hehe.
Anyway thanks, as this was the next piece of info I was hunting for!

In charging after fully discharging the phone, do i charge it while it is off or can i charge it while it's on?

Battery calibration by deleting the file is now known to be complete snake oil. Confirmed in the code as well. Deep discharge cycles, along with heat, are enemies of Li ion batteries. While it seemed a very good idea at the time, following this procedure is now known to be only detrimental to battery life, even if it makes people feel good.

Jeff is correct. Since these instructions the myth about battery calibration has been debunked

Keep the phone between 20-85% otherwise heat will destroy the battery. Charge the phone as often as you can and avoid extra heat from charging.

help..
pls help me.after doing battery calibaration?my battery % was 0 only.how am i gonna fix that?even though i charge so many times.it get 0 % only.pls help me fix that problem.tnx

Necro-rez of a tread that has already stated "don't do this" ain't gonna fix it for you. Why don't you post what your hardware, firmware, and software are in another thread, along with very clearly detailed description of what you did and what happened (with what you expected to happen, if different).
Without that, "Not a bug" "Move along, nothing to see here."

after pressing "calibrate" from app and unplug phone from charger, do i have to let the phone discharged without it being disturbed from any battery usage activities e.g. messaging, play games, browsing internet etc? or I can use the phone while it discharges? i hope to not defeat the purpose of calibrating the battery.

There is no purpose for this kind of "battery calibration" process. It has been thoroughly debunked. It is generally accepted, however, that deep cycling of the batteries shortens their lifespan.

do i need to charge it off, after draining the battery ?

[Q] Wrong battery percentage???

Hello all!
Ive noticed rather unusual thing. For example - when i get around 50% of battery left i can reboot the device and get about 80% but of coz its dropping faster then normal charged %.
Iam on mugen 1950 mah and have done wiping battery stats and done the calibration.
ROM - HyperNonSence 1.5 with faux 006u kernel.
Any suggestions?
Thanks all in advance!

Yeah this has happened with every Android phone and every battery I've had.
Don't think there is anything you can do about it to be honest. You could reboot it again and sometimes the indicator will fall closer to where it was before.
Or you can use it i.e. play a game or browse the web and usually it will fall to a more accurate level.
Alternatively, just plug it back in and wait till it charges to 100%, unplug and then reboot. If it is still green then it's likely charged fully.

So, it stays 100% after reboot rly long, its true fully charged.
Iam not crying about my battery life, i think its OK, but it can be better of coz =)))
F.e. on my HTC G2 i havent got this problem - percentage raises only for 3-5% after reboot not for 30% like on Sensation. BTW both batteries are Mugen.
Maybe i should try Mugen calibration tool? but seems to me its just a simple original calibration tool.
But TY anyway =p

Wiping the stats through recovery did not help? I do this with every new rom. Perhaps a app from market might help?

[Q] Battery level has gone crazy

Hey all,
recently I have encountered a rather big and annoying problem on my phone. It has to do with my battery. I've looked it up on xda, but nothing was really exactly like my problem.
The problem is that my battery level has gone absolutely crazy.
First, charging my phone takes many many hours. After around 5 hours it still wasn't fully charged.
Then when rebooting the phone, it magically said 100%. However, after this the phone drained extremely fast. Think around 20 percent per hour, while using it normally!
Secondly, around 40 percent the phone automatically turned off, without the usual HTC logo. When I turn it on again the battery level is suddenly 2 %. After a few times turning off and on the battery level goes up to 30 percent. This can be seen very well on the pictures.
The phone is 1,5 years old and I haven't installed a custom ROM.
Am I dealing with a broken battery or is the problem in the software?

Hi,
I'm not an expert, but I think your battery is exhausted.
But before you run buying another battery...
What charger are you using? Stock HTC or custom? If custom, what are the Voltage/Current output values?

probably your battery is dying as the above user said
or the battery it doesn't connect properly
check it

While reading on some forums about a better battery for the Sensation I haven't encountered Mugen, only Anker, which has some good reviews.
