Turn off bluetooth, beam, wifi, data connections
Ensure your phone hasn't got automatic updates activated for anything, i.e. weather/stock/emails etc etc especially if set to update every 30 mins etc
Also in wifi settings, ensure wifi is set to 'best battery'
You could also dim screen slightly either permanently or after a period of time if not used.
Also check if any apps installed are working in background eating up battery
Simple things like these should help.

Good hints so far ...

Nice link, reading over this myself to see if I can improve my own

TY guys, but I have already did all of those hints to my phone, don't you think it could possibly be my SPB Shell 3.5.3 ? :S

Here's what I do to find out my Battery Life Time:
- Flash ROM or Hardreset
- do not install any App or activate automatic Updates for at least 2 - 3 days (at least 3 x Full charging Processes) to find out the Battery Time on the naked ROM
- do a little Log (how many calls ... how many SMS ... high usage over the day ... low usage over the day)
- after these first days activate only things inside the ROM (eMail ... WiFi ... Weather ... what ever your ROM delivers) => still don't install anything new on your device (again for at least 3 x Full charging Processes)
- write your findings down
- Install Apps ... but ... only one at the same time
- monitor the behavior of your Batt
- You can also use Tools like BatTest or BattLog to get "better" (measurable) results
That way I found some Taskbar Modification and other Tools to be Battery eater (nice Icons but short BattLifeTime)
Good look
fwt

battery log says: 71% (dunno about what), 3,912v, 3,4ºC and 280ma; is this good for my phone? :S
Questions:
1: what is a ROM?
2: what means flashing it and what could it fix? :|
please, help me >.<, I got out from my home today, leaving the phone with 100% battery life, but when I came back (5 hours later) it was 70%.

[Howto]Tips n tricks for better battery life

Since we have better battery life on Android r169 version thanks to our devs i'm going to post tips n tricks for a even better battery life
1. Use "GSM auto (PRL) to save more juice while still connecting through 3G
- in the phone setting>wireless and network>MobileNetwork>NetworkMode
we are only allow to choose GSM only/ WCDMA / Auto between two
- but if you use type "*#*#4636#*#*" to phone Information, you can choose more type of networkmode. It is claimed that choose "GSM auto (PRL)" allow you to save more battery (cell standby) while allow you to connect to 3G network.
-there is one more setting which you can change:click settings(windows logo)>select radio band and change it according to your needs
- Please provide feedback on this. Thanks
2. Use AutoKiller Memory Optimizer
- This tool is different from other app killer
- It fine tunes android systems inner memory manager to keep your device fast over time.
- As a side effect it also lowers battery consumption.
- At certain free memory level (e.g. 250mb), the android os will automatically close those apps not in use (according to original android os logic)
3.Use Autostart
- Instead of closing them, it would be better if we don't let the app start from the begining
- You can choose to disable those app that u feel unnessary, so that they will not run during your phone startup
4. Check your Battery Consumption
- Download "Current Widget" or "battery monitoring widget" from market
- these apps will monitor your battery usage and recoded in a log file
- This is the normal consumption rate (varied across ROM, kernel and CPUI frequency and other factors)

Tips
General Lithium-Ion Battery (LIB) Usage:
• Discharging your LIB fully (or less than 2.4 Volt per cell) is bad for the battery. Every time you do that, it can be said that small part of your battery (some cells) dies (they forever lose their charge). Do not store your batteries depleted, there's a high chance they will die completely or will become very "weak".
• You cannot restore bad LIBs by overloading/heating/praying. You gotta go buy a new one. They DO degrade overtime, some cells naturally lose the ability to gain/give electricity.
• Although it is said that LIBs do not have memory, it's not entirely true. LIBs have gauges that monitor performance of cells, and if you do a lot of small charges, it won't let those gauges to monitor a full battery potential, causing an invalid indication of charge level. A complete charge/discharge should be made when battery capacity seems reduced, that will calibrate gauges and they will provide your phone with correct charge level status. A full charge/discharge cycle should be done every 30 (or so) partial charges.
• LIBs have a shelf-life. Do not buy them to store them. Use them early, use them often, they will die whether you use them or not. Do not buy LIBs to use them in 6 months/year/etc, buy them right before actually using them.
• LIBs have short lives (in comparison to NiCa batteries, etc). You should expect to buy a new battery in 2-3 years after being manufactured. It is caused by internal oxidation and there's nothing you can do to stop or prevent that.
• Worst LIB treatment is to keep it at 100% charge level at high temperature (think laptop/phone under direct sunlight, like car dashboard).
• Best LIB treatment, or LIBs "favorite" charge level - 40%. That's also the usual charge level you buy them with.
• LIBs don't like heat. For example, while always at 100%, typical LIB in a laptop, at temperatures of 25C (77F) will lose 20% (twenty percent!) of full capacity per year. That capacity loss is reduced to 6% (six percent) at 0C (32F), and increased to 35% loss at 40C (104F). So, keep them cool (LIBs like fridges), don't let your devices sit in the sun or overheat at charge. Also, keep in mind that while in use, battery will be significantly hotter than phone/outside environment.
• LIBs like frequent partial charges/discharges more than they like full charges/discharges.
General Android power usage advice from google:
• Although this part is somewhat controversial, they do recommend having a complete, full FIRST charge to be made. If time allows, a preferred time for the first charge is 12 hours. This may have more to do with the OS than the battery.
• Battery on a Android device, in average, will last about a full day with normal use (some videos, mail, calls). That's what you should kind-of expect.
• Speaking in averages, "idling" 3G/EDGE connection (when phone is sleeping and no data is transferred through 3G), drains almost no energy. Just a little more than having 3G/EDGE radio off completely. So when no apps are using 3G, you don't need to keep it off.
• Same goes to WiFi connection - although it's on, if there is no data flowing through it, it uses almost no energy.
• At full throughput (100% data flow), EDGE is using more energy than 3G. In average, 3G is more energy-efficient than EDGE.
• WiFi is using more energy than 3G (when both are at 100% use), but since it transfers files much faster and then goes to "sleep", it's actually recommended to use WiFi whenever possible. Since it'll "sleep" more often than 3G, overall it will use much less battery than using 3G.
• Some bad apps or widgets can use android's "WakeLock", keeping CPU at 100%, screen always-on, or both. I myself have encountered such widget (I won't mention the name, it's in the market) that used a WakeLock to keep CPU spun-up at 100% all the time. That makes a huge impact on battery life. My advice - use a CPU profiling app to monitor the CPU - make sure that CPU slows down by itself when it's not used. So, beware of such widgets/apps. To check for CPU cycles, many recommend OSMonitor (free from market, install it, go to options, sort by "Load" in descending order. It'll give you "busiest" processes at the top). At rest you should be getting about 10-20% for OSMonitor itself, and 1-10% Android System. At rest, everything else should be 0-1%.
• Android slows down CPU when not in use by itself, as a built-in feature. Apps that throttle/change CPU frequency, are not necessarily needed.

Standard battery Capacity: 1200 mAh
HTC HD Mini have a standard battery Capacity: 1200 mAh.
When the battery loses capacity and you want to replace it, consider that there are batteries in the market for the HTC HD Mini with 1700 mAh Capacity, which would be logical to give a day or two extra pleasure

did you install apps after that?if yes,which?
do you have GPS on on droid or on wm?

With "CurrentWidget" you can also log applications which are running on background. Then it should be easier to find out cause of battery drain. Also don't forget to write about your current settings ...

HOW to check your battery life ( HTC HELP CENTRE )

Today i contacted HTC Center to ask them about the battery drain issue and overheating happes after updating to ICS they didn't give me a quit good answer for all they questions but,, they give a way to check battery life ..
NOTE: if ur device dzn't pass this send it back to repair
1ST A range of 10-20 hours of battery life is normal based on individual usage patterns, you may try dialing *#*#4636#*#* to check the battery information including health and status.
To optimize the performance of the battery follow the below:
1. turn off Wireless connections (Wi-Fi, Mobile Network, Bluetooth) when not in use
2. Stop services and apps running in the background by going to menu> settings> applications> Running services> tap the service you want to close> tap stop/Close.
3. Adjust the display settings to where it uses less battery and meets your needs
Here are also some tips for you to conserve battery life if you are experiencing this issue.
? Try rebooting your phone every few hours. Rebooting your phone clears the phone internal memory and shuts down programs that may be running in the background and using battery.
? Try turning off the data connection when not in use. Data connections in the background and syncing can cause the phone to use more battery even when sleeping.
? You can set your display to brightness to auto. Allowing the phone to adjust the brightness allows for optimal viewing while conserving as much battery as possible.
IMPORTANT
You may also try the battery test, by following the instructions below:
1. Restart your device
2. Turn on Airplane Mode
3. Connect your device to the charger, and charge it fully
4. Set Screen Brightness to Max.
5. Set Screen Time out to never.
6. Dial *#*#3424#*#*, choose battery run down test, and follow the instructions.
NOTE: If the device loses more than 40% of battery in an hour, then send your device to the repair center for repair.

Sorry to burst your bubble but these step will actually reduce the battery , if your phone drains a lot and heats up you have a faulty device that's it.
If you reboot often phone consumes a lot more by loading everything AGAIN it wont save your battery at all.
Autobrightness doesn't always work , its better if you manually set it to 35%- 40%.
Turning off wireless and data will conserve battery that's like smartphone 101 , who doesn't know that?
Android and particularly ICS automatically terminates unnecessary background processes, there is no point in killing them. In fact if you do that often it will consume more battery to start them again if they are needed. Just remember to swipe away apps after you're done, ICS will take care of the rest.
As for the battery tip , after you initiate the test phone will ask you to turn airplane mode on, it will also keep the max brightness level and wont turn off the screen so there is no need to perform the steps you've posted.
posting to keep it alive lol

i didn't either convinced with there answers as i told they wasn't direct ....
this is just a test nothing else...
and about overheating and reboots it's only happen to allot of people after ICS update
i do normally after flashing any rom set the brightness to 35% ..
lol
i did the 1 hour test and my battery level get down to 74%
the battery heat was between 32.3 to 43.7 C

While I agree with you on most of the other points, this one needs a bit of explanation. Although, the memory management in ICS is far better and is a bit like what Windows Vista and 7 do, at times you do need to kill some messy programs which play with system privileges and hog battery, like the famous facebook application.
GB and ICS use in-memory program caching like Vista and Windows 7, i.e. they keep frequently running programs in RAM and use as much memory as possible (or in sane limits in case of 7) for this task. It is freed automatically if a program requires more RAM. Thats why even when a large part of memory appears to be consumed most of the times on ICS/GB and Vista/7, large program still run perfectly well. The OS is just consuming the RAM that is lying around when no program is using it. GB and ICS even introduced a "Cached Applications" view in their "Running Apps" screen to take a look at these cached apps.
This makes the killing of background processes optimized for the OS as processes which are not used for long time can be marked inactive first and then cached. These cached processes can then be removed in cases memory is required by some program.
But there are some nasty apps like the Facebook app which not only keeps processes in background, but also keeps them active and mark the services spawned from the main executable as system services hence they are not killed at all. Facebook's background upload system, the so called "push notifications" service, all these take CPU and other resources all the time and dramatically reduce the battery life. Hence killing these manually is still required.
This is my personal experience or perception or whatever.

What you're saying is true but its still not accurate. As you mentioned facebook is marking its processes as system service which means it gonna try to start again automatically. As I said before there is no point in killing, also facebook made some improvements in this area. I remember that old version was using about 40mb of ram when it was idling but now it uses about 8-9mb. As for the push notifications I've disabled them so I cant comment on that but I do know that its not always working.

You may as well talk to a wall.
This guy makes stuff up and posts it as fact, then begs for thanks for his posts. He claims he's an expert but doesn't know the most basic things about how Android phones work.
I mean for crying out loud....ICS is well known to add about 20% to battery life. It's one of the best features of the new version. There were countless threads about the improvement people saw when first switching to ICS a few months ago when it first started to come out. Yet this thread basically suggests that it's a known fact that ICS causes increased battery drain.
Taking his advice is somewhere between counterproductive to your goals and downright dangerous to your device depending on what he's suggesting.

Guys, please stay on topic. There is no need to call this guide "dangerous".
His points might not bring any advantage but they are not dangerous either.
Neutral discussions are okay, but please don't start attacking each other.
We are in a forum were we want to help each other and not having contests on the best guides or whatever.
I won't comment every single point made here, but both sides have their rights and wrongs.
So please keep this technical.

When you suggest mixing and matching elements of different versions of hacked firmware, that most certainly is dangerous. (For the phone anyway)
So much can go wrong doing a thing like that.
And when someone is recomending doing that as a sollution to every new problem someone suggests without regard to ROM, current firmware, the specific problem, android version, etc etc.....that is irresponcible.
Thats what this guy is doing in several other threads. This thread isnt one of the damgerous ones. Its one of the counterproductive ones I mentioned.
Someone will screw up thier phone with this advice. Pointing this out is not insulting to 1 person. Its being helpful to hundreds.
If we just sit silently and not say anything about bad advice, we wouldnt be very good forum members.

and the other thread you talk about is proofed with video and photo's and cleared how to use it with the right firmware with specific ROM so stop this chasing out and don't make ur self looks like a hero we all here support each other to provide a good solution for other's so keep it that way end of discussion.

Ok final warning regarding attitude to all.
If I see any more of this there will be consequences to all.

Not true. No documented cases of it harming the Sensation. 3.12 and 3.32 are very similar. Also, with the development mode flash fix coming out any day now, even if someone bugs up their hboot or something, it'll be recoverable similar to how Samsung phones to use ODIN to completely flash back.

There is no way to change it.
It propably protects the battery to become too empty without getting your device plugged in time. "Too empty" means that sometimes if you drain your litium battery empty totally, it wont start to charge it at all. So it is there for protecting you and your device without having next problem not being able to charge it.

Have you ever investigated this subject that you are so sure? If you cannot do it - don't assume that no one can.
I don't also see any relation between dimming the screen and protecting the battery of getting broken. If 5% level is a level on which the battery should be charged because of the damage risk, then it would be absurd to dim the screen (ie take an action aimed at saving the remaining power so the user can work a few minutes longer on the last remaining 5% until it reaches 0 or 1% = drain battery even more = in your theory: increasing the risk of the damage even more), and not to turn off the device at all. Be aware, that Samsung indeed implemented a protection aimed to secure the user of the risk of breaking the battery (well, I don't think it's the clue anyway - iI guess the main purpose is in preserving user of data loss/filesystem corruption, which is possible to occur when the system is being shutdown in an "immediate" way, without chance to perform shutdown sequence properly) due to full discharge, but it is triggered on 0 - 1% level and is resulting in starting a "regular" system shutdown, aimed mainly to save all the working data before user loses it *** See comment at the very end of my post for additional info about changing this behavior, which is confirmed to work by myself...
It is almost ALWAYS possible to mod behavior of the system, especially by decompiling system apps and modyfing smali, which is not extremely difficult/impossible by the way, as the community has released such a solutions for many issues/feature requests, concerning even n8000 itself (ink lockscreen, syscope disable, power menu, flashable themes...).
In this case, I can see another possibility, which is even less intrusive to the system; AFAIR the percentage level of 5% is not embedded in some system or framework app, but it is defined in one of the system's apps preferences (guess settings provider? dont remember...), in sqlite database. And sqlite database can be easily accessed and its content can be modified by sqlite tools, ie sqlite3 binary from command line, and even some apps from play store. Then, you shall be able to lower the value to, for example, 1%, so the screen backlight will be turned off with further delay, ie. at REALLY critical power level of 1%..
EDIT: Didn't found above setting, dont have time for this, but found another one (at database lying at com.android.provider.settings) - "dim_screen" which is set 1 by default. Maybe changing it to 0 with any SQL editor will force NOT to dim screen at all.
An for the begin, I have a solution that is very very very possible to work...
As for now, I have not tested it, especially if the critical battery level setting (default 5%) has direct relation to the battery level on which screen is dimmed, but I am ALMOST sure about it, as the crtitical level setting that I am talking about (no matter where it is stored...) is recognized system-wide.
Oh, almost forgot, the solution!!!
Install Xposed Framework (search for it on xda if u dunno what it is) + module XBatteryThemer - apart of other options, it has the option to lower critical battery level (as well as two other levels, which determine displaying the low battery alert popup) to as low as 1%. Your screen shall no longer dim at 5%.
*** actually, there is another one Xposed module (CriticalBatteryShutdown, or something...?) which can force the device not to turn off when battery reaches some level between 0 and 1%, which is arbitrary action by default. With this mod the device is working untile theres really no power left, which sometimes can give you additional 10 minutes. A

Please correct me if I´m wrong, does that make sense to you if your battery is 5% and you thinking of raising the slider higher ? Maybe you should check your energy saving settings. My two cents.

Have you ever investigated this subject that you are so sure? If you cannot do it - don't assume that no one can.
I don't also see any relation between dimming the screen and protecting the battery of getting broken. If 5% level is a level on which the battery should be charged because of the damage risk, then it would be absurd to dim the screen (ie take an action aimed at saving the remaining power so the user can work a few minutes longer on the last remaining 5% until it reaches 0 or 1% = drain battery even more = in your theory: increasing the risk of the damage even more), and not to turn off the device at all. Be aware, that Samsung indeed implemented a protection aimed to secure the user of the risk of breaking the battery (well, I don't think it's the clue anyway - iI guess the main purpose is in preserving user of data loss/filesystem corruption, which is possible to occur when the system is being shutdown in an "immediate" way, without chance to perform shutdown sequence properly) due to full discharge, but it is triggered on 0 - 1% level and is resulting in starting a "regular" system shutdown, aimed mainly to save all the working data before user loses it *** See comment at the very end of my post for additional info about changing this behavior, which is confirmed to work by myself...
It is almost ALWAYS possible to mod behavior of the system, especially by decompiling system apps and modyfing smali, which is not extremely difficult/impossible by the way, as the community has released such a solutions for many issues/feature requests, concerning even n8000 itself (ink lockscreen, syscope disable, power menu, flashable themes...).
In this case, I can see another possibility, which is even less intrusive to the system; AFAIR the percentage level of 5% is not embedded in some system or framework app, but it is defined in one of the system's apps preferences (guess settings provider? dont remember...), in sqlite database. And sqlite database can be easily accessed and its content can be modified by sqlite tools, ie sqlite3 binary from command line, and even some apps from play store. Then, you shall be able to lower the value to, for example, 1%, so the screen backlight will be turned off with further delay, ie. at REALLY critical power level of 1%..
EDIT: Didn't found above setting, dont have time for this, but found another one (at database lying at com.android.provider.settings) - "dim_screen" which is set 1 by default. Maybe changing it to 0 with any SQL editor will force NOT to dim screen at all.
An for the begin, I have a solution that is very very very possible to work...
As for now, I have not tested it, especially if the critical battery level setting (default 5%) has direct relation to the battery level on which screen is dimmed, but I am ALMOST sure about it, as the crtitical level setting that I am talking about (no matter where it is stored...) is recognized system-wide.
Oh, almost forgot, the solution!!!
Install Xposed Framework (search for it on xda if u dunno what it is) + module XBatteryThemer - apart of other options, it has the option to lower critical battery level (as well as two other levels, which determine displaying the low battery alert popup) to as low as 1%. Your screen shall no longer dim at 5%.
*** actually, there is another one Xposed module (CriticalBatteryShutdown, or something...?) which can force the device not to turn off when battery reaches some level between 0 and 1%, which is arbitrary action by default. With this mod the device is working untile theres really no power left, which sometimes can give you additional 10 minutes. A

Did I say that 5% is the minimum level? No, I didnt. All I said it is, it gives you more time and IF you drain your battery EMPTY, it may not charge. Of course there are self-protection manager already, but as you know, they dont always work as they should. There are several questions on net what to do when the phone doesnt start charging because they drained the battery to a state to auto-shut off. I dont understand why anyone would like to drain the battery almost empty and in a bad scenario you have a dead battery. Will it happen with your device? Maybe or maybe not. And it is not even healthy for a lithium battery to let it full disharged/cycled on everytime.
And yes I have read that there are apps that allows you to change this but only if your device is rooted. Never tried, mine is not rooted.
This will explain it very well: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

No, you cannot set the brightness by a slider when the battery level is 5%. It automatically goes to a state to save the battery. It is built in the system.

Battery Monitoring

I have noticed on my OPO that the application "Battery Monitor Widget" doesn't appear to have access to accurate battery information, including the size and the recharge/discharge rate. Instead you have to configure it manually for the size and tell it to estimate the discharge/recharge rate. From a bit of testing, it doesn't even appear that the OS itself has a good view of the battery, where if you have enough applications drawing enough power, and not enough power feeding the phone, it won't even show as being connected to USB power, and it will estimate if it is on AC or USB power apparently based on how much the recharge rate is.
My first question is if anybody knows if this is a software only issue, where additional hardware support needs to come in an update. Alternatively, are there any other tools that allow accurate monitoring of power state? Thanks!

I noticed the same thing. Mah shows 0 usually. I was also looking for an alternative, but i guess an update will fix it.

Change the battery monitoring setting to reverse mA. You can also manually input the capacity of the battery.

It may just be at random, but when I set reverse mA, I found that the system wouldn't go into deep sleep while charging, which slowed down charging significantly. I'm also pondering what this actually means (the reverse mA) as this implies it has data that it is reversing in some way.

I heard that "Kitkat" has changed their policy so that any battery monitor apps have no any more rights to read the figure of battery information.
But, the solution, as per what i experience, is to download Xposed Installer, and then there is a module named "Enable BATTERY_STATS for KitKat", download and activate it. After that, any apps with battery monitor function can be executed sucessfully.

As of the newest CM 11S build and battery monitor widget, it appears the issues have been resolved, and the battery data appears to be more accurate. This may require root however.

And there is a helper app which you need to install. As far as I recall
