battery drains fast? now here an oldschool solution

Everybody knows the problem of battery draining in our beloved Cappy
I found an oldschool solution.
Drain your Cappy's battery to the end
enable gps
no battery saving mode
enable wifi
Maxed brightness
After that let it charge for the night until it's 100%
After startup it will show you 97% but its 100%.
Im with wifi for 2hr and the battery draind only 7%
Also hope that this solution is not like "thanks captain obvious"
hope it will help's u, share your findings after using this method.
Using perception 10.4 and speedmod k13b
Sry for my bad english...

I will try you old school method

Old school method worked on old school NiCAD batteries that suffered from memory. New school LiON batteries do not.

Ok for me. I simply restart my sd gingerbread androïd. And my android consums only 6mA in sleeping mode.

If you haven't done it in a while for a Li-on device it will recalibrate the charge controller, but it doesn't increase the actual chemical capacity of the battery like it would for NiCad.

Draining Li-On batteries completely is bad for them.

I've heard it's only bad if you leave them down for more than 12-24 hours. If you put it right back on the charger, I think it's good once in a while. That's that Apple recommends for theirs, anyways.

Heat is the enemy of any battery. The lower you run it down the longer it will have to be on the charger to get back to 100% and thus the longer it will be exposed to heat. Calibrating the battery and then wiping the stats should be all you need to do. I easily get 25-30 hours out of my battery with moderate use and I rarely let it get below 30%. And if I listened to Apple I'd have an iPhone.

Yeah, but these devices often get run down and charged. I think Apple's right on this. FYI, that's about the Macbook, which I have one, not the iPhone (don't have one of those).

Here's what TechRepublic had to say about it:
Lithium ion
Of the types of batteries mentioned here, lithium ion cells have some powerful advantages. They have an energy density of 150 watt-hours per kilogram. Like NiMHs, Li-ion batteries have no memory effect. That is, they don’t lose the capacity to fully charge if they aren’t fully drained. Left on the shelf, they lose the least power. Their discharge rate, at 10 percent per month, gives them a good storage life (but they must be used within two years of manufacture). This means that you can grab one that you charged up three months ago, and it will still have about 70 percent of its charge left. If you’re maintaining a number of laptops, that’s good news.
These batteries also have some important disadvantages, however. They have a volatile chemistry. Each lithium ion pack in your laptop must have its own electronic protection circuit that protects against overcharging, over-discharging, and too-high current. Each cell of the battery pack incorporates a built-in safety vent. All three battery types have a safety vent, but unlike NiCad and NiMH batteries, which can withstand some overcharging, the vent in lithium-ion batteries is designed to disconnect the battery permanently if it ever has to be used. It does not reseal. The potential danger of this type is why Li-ion batteries come as a sealed unit including safety electronics. As a helpful part of the circuitry, each Li-ion battery provides a charge indicator. Pressing a button will cause a row of lights to be lit, indicating the charge, as shown in Figure A.
I was surprised to learn that of all the batteries, lithium-ions have the worst useful life. Though they have a slow discharge rate on the shelf, all Li-ion batteries irreversibly lose capacity over time. Even after one year, they lose the ability to be charged to full capacity. Cadex tests indicated that their practical service life is only two years. According to Cadex’ document, Batteries for Mobile Computing, “Li-ion batteries should not be stored for long periods of time but consumed like a perishable food.” On the other hand, while they don’t deliver as many cycles as NiCad batteries, they do provide up to 1000 cycles if they’re used within that two-year lifespan. They are also maintenance free. Not only do they suffer no memory effects, they don’t need to be periodically discharged and topped off. Like NiMH batteries, shallow discharges actually increase the number of cycles. Unfortunately, these cells are expensive. Keep in mind that your IT department might be better off with a smaller, rotating inventory.
As you can see, there's nothing to be gained by discharging them completely. BTW, Apple laptops have circuitry that prevents the device from discharging the battery completely to prevent damage. I'm not sure our phones have this, so their advice should not apply here.

Android only lets the battery discharge to ~40%, WinMo6.5 to ~30%.

The point is (was) that there's no memory effect and therefore no valid reason to be discharging these batteries completely. The "old school" method just doesn't apply here and could actually shorten the battery's life in terms of charging cycles.

Define moderate use? I struggle to get over around 14 hours of use. Usual stuff includes 2 hours of music, maybe 50 to 100 text messages, up to 5 minute of calling (rarely make calls), and little to no WiFi or games. I do use the data network a bit, having Facebook and Twitter and stuff syncing every hour. But overall, my battery life sucks.

That's actually not bad for everything you describe. Remember in a smart phone the more the screen is on the faster the battery dies.

And if you're syncing in a mediocre (1-2 bars) network coverage area it takes even more power than when you have 4-5 bars. I generally have about 2-3 hours of screen on-time between charges, several phone calls and texts, e-mail pushing every hour, some game playing, some BT on while in the car, some Market/web surfing and every other day I track my MTB rides with GPS while listening to music via BT. I put the phone on the charger every night, but I do carry a spare battery just in case. I wasn't getting this kind of battery performance on Eclair, though.

[Guide] Everything you wanted to know about Li-Ion batteries but were afraid to ask!

DarkDvr said:
So after noticing how much of a difference people get in their battery lives, I've decided to do some research and make a guide-line that will give us all we need to know about properly using our batteries. First part is a general information and usage techniques for LIBs, second part is taken from Google materials on Android-powered devices (G1, Magic, Droid, Nexus One, etc).
Sources:
Wikipedia - http://en.wikipedia.org/wiki/Lithium-ion_battery
BatteryUniversity - http://www.batteryuniversity.com/parttwo-34.htm
Google IO Conference 2009 - http://www.youtube.com/watch?v=OUemfrKe65c
Electropaedia - http://www.mpoweruk.com/life.htm
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.
• Car "fast-chargers" overtime degrade your battery a little, as they give too much energy to the battery too fast (high voltage). Trickle-charge (USB) is best. They do provide an initial higher capacity charge (high-voltage), but do degrade the long-term battery capacity. General idea is that the slower the charge - the longer (long-term) battery will serve you.
HTC/Google-specific advice:
• 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 significantly more energy than 3G. 3G is much 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 (at least on Nexus One) slows down CPU when not in use by itself, as a built-in feature. Apps that throttle/change CPU frequency, are not necessarily needed.
Please correct me if I made a mistake somewhere, but all this info comes from those reputable resources I mentioned above, I didn't make any of it up.

Quoted from the nexus one general forum, I guess it would be a good tip for captivate users since battery has always been a great concern, If this is counted as a double post, feel free to delete it.

"Almost no energy" is a load of bull****.
20-30mA is a lot of energy.

Good stuff. Knew some, learned more, found out some of my prior "knowlege" was in fact borderline wrong. Thanks for posting.

I think our AMOLED uses a more than the "LCD Normal" example given in the graph. A lot more.

Bear in mind this is quoted from the nexus one thread so not everything applies to the captivate. Probably just take into account ways to extend the shelf life of your lithium battery.

Thanks!!! This is really interesting!

good info thanks for posting

The problem with most apps now a days is that there is very little time when the radios (EDGE/3G/Wi-Fi) are not being used. If someone uses a push email, it's constantly keeping the data on waiting for email to arrive, and it KILLS battery life. I started using Juice Defender to force my data apps to do what they should be doing according to the info above; enabling data enough to update apps, and then disabling data until it's needed again. My battery drain went from 5 hours to dead phone to well over 24+ hours. In one case, I used 24+ hours on a 50% charge!

[Q] Real World Battery Life

Fellow MT4GS users,
How is your battery lasting you? I'm coming from a MT4G, even though I eventually modded it, and it I used to get at least a full day and have to charge that night at the worst unless I really heavily used it.
My MT4GS has been lasting me half a day or so before I get into the yellow/red and I'm usually charging before the sun goes down.
My main culprit according to the built in battery indicator is display at 65% (I'm on automatic brightness)
Just over 10 hours today for me before I had to charge.
ps- Anyone know how to remove the annoying low power notifications? I'm getting two pop ups in a row.

Yeah mine generally lasts about 14 hours at moderate usage, but it's only been 2 days, and I remember when I got the MyTouch 4G it died on me while I was still at work and then after a week or so it got much better...

Yeah, I can agree with you there I think my MT4G was a little wonky the first week or so. We'll see how it goes.

Only lasting 6 hours yesterday ....

My battery lasted about 33 hours. After the 1st full charge. So way better than my other phones have done. This wasnt heavy usage though. No videos or music just a few calls, lots of emails and some web browsing.
One problem I am having is low call volume. My videos and music are perfectly loud, just the call volume sucks.

Well make sure, your phones screen brightness is on low. Also make sure wifi,gps,bluetooth are off. Also make sure you kill some of the apps you ran on a task manager. just gotta find ways to keep the battery life up.

Well when I first got the phone, I didnt charge it until it was almost dead. Then fully charged it.
Also I turned off GPS, WiFi ect. I also use task manager to kill background programs that I don't need or want running.
We will see if the battery life goes down after a few weeks. Sometimes they take time to normalize.

Oh what task you ended and what task manger you used?

I appreciate the help but the logic is off. This is the latest ..and i stress smartttphone. It is supsupposed to be used as such. Bluetooth ..4g..music...video calling..maps..etc.. if u use of of these features six hours it will last. If you use them all try maybe 4 hours. Plus those boxes are annoying when the batterly is low. This phone has got to be rooted.

I'm gonna have to agree with that one, that's pretty much no different than saying buy a car but don't drive it so you can save gas lol

I have gotten to around 12 hours or more now. Still moderate overall but heavier browser usage.
I do not kill tasks or turn off wifi, gps or anything. My brightness is auto.
I uninstalled the recent maps update because I saw where G2 users seem to think the recent update is draining their battery so I wondered if it could maybe be causing issues here too.
Anyways my battery life has gotten into the acceptable range and that was all I really did other than have more days to monitor it.

Some technical specs on the battery:
Model: BG58100

This appears to be the same battery that is in the Sensation 4G according to Google.
For us this is good because Ebay and Amazon are already flooded with replacement batteries.
We need to find a higher capacity mAh battery but with the same size as to not make us have to get a replacement back. This shouldn't be that hard.
My old phone has a smaller battery with a higher mAh capacity so the battery in the myTouch 4G Slide is an utter disappointment. They could have easily produced a 3000 mAh battery for this beast of a phone.
Edit: Found a 1900 mAh battery for only 9.99.

Screen is on the least bright setting. I'm an ex blackberry user and dont even have one app. I could care less about apps. I'm charging every 5 hours and thats sometimes from just it sitting around/ not even using the phone. The thing better get it's act together. I'm starting to like the keyboard too but I'm up at 5am and if im charging at noon that's terrible. Especially with minimal use.

Weird I live in small city and 4G is crazy fast. When I get to a big city like Baltimore, Maryland the 4G was slow. My thoughts are there too many people on the 4G network. T-Mobile did promised us double the 4G speed and they need more Towers too.

~
For the first couple days, my battery life was awful. I'd be getting low-bat notifications when I got home from an 8-hour day at work.
But of course that's always the case with new phones that haven't even had the settings tweaked...
- Placed a Wifi toggle widget on the homepage and turn it off every day after leaving home for work in the morning.
- Ensured certain programs and updates were not running in the background automatically:
~ Turned off Autosync on accounts (manual only)
~ Turned off autoupdates for weather
~ No Bluetooth, GPS, Wifi, unless turned on for a specific reason
~ Enabled power efficiency and power saver modes (30%)
~ Disabled Always-on data connection
~ Disabled auto-updates in various apps (Friendcaster, IM+ Pro, etc.)
- Turned the screen off when not in use
Today I'm at 40% after 14 hours of mixed use. I'd say that's DAMN good.
By the way, for those seeing the whole "Autosync off" thing and thinking that you can't do it, just do it. I don't get my work email or personal email on my phone unless I tell it to and it's utterly awesome. Less stress. Less looking at my phone constantly. It feels free and just plain great. And I used to be superconnected 24/7 syncing every 5 minutes (if push wasn't available).

Thunderbolt lives, READ ME.

Many people have argued that since the thunderbolt has not been updated with gingerbread that it will die out and be worthless. I'm here to tell you that is not the case at all.
Those with the bolt will tell you that their main problem is the battery life. This is exactly right but I have setup my phone that allows my phone to last for days without a charge. Also this does not require you to root your phone, so this will work for everyone and silence all the retarded people who keep posting that its dead. The two biggest factors is of course 4G and the display that eat the battery most.
Make no mistake about it tho, HTC implementations along with the hardware on this baby still takes the cake for flagship of Verizon.Don't be fooled by the dual core hardware, good in theory but let's face it phones aren't their yet, apps don't need two cores but more RAM would be nice.
Read this if you want your phone to live. I have reached 60+ hours unplugged, I am an IT network manager, I know stuff so leh dew it.
1. Get the extended battery. No matter what type of Android phone you have you are going to need it, especially without gingerbread. This is 4GLTE inside a laptop, do those last more than a few hours? ill answer for you, NO.
2. Disable what you don't use. This is why widgets were made to disable data, WiFi, Bluetooth, GPS, etc. when not in use. Get a new brightness widget by curvefish set it to 25% and as well as turn off the animations if you really want more improvement. Disable always-on mobile data, as well as roaming, and manage your email accounts so they sync manually. As far as location goes just use Google services, GPS standalone is a drainer.
3. Create setting shortcuts on the home screen. Add accounts and sync so you can disable auto sync and background data. Background data is only used for the market learn to disable it fools. Add a shortcut to running services as well to keep the RAM usage to a minimum.
4. A main issue always discussed is the bloatware app of blockbuster. Make sure you enter the program and disable automatic movie updates. Then go to running services and disable both instances of PVMtpservicestart and PVWmdrmService. You will have to do this every time you REBOOT but not fast boot.
5. For gods sake, don't be a fool any longer! HTC gave you some of the best widgets but use them wisely...just because you have 6 screens doesn't mean use them all. One widget app that will be loved by all is widgetsoid, extremely useful. Even the HTC clock has separate animations that can be disabled if needed.
6. NEVER by any means should you use any type of juice defender or task killer. It does more harm than good even with Android Froyo 2.2 can still manage this. Download apps such as battery indicator tht shows your battery in increments of 1% and doesn't use any resources in the background. Don't be the fool that gets apps cus they are cute and have no use, you are better than that, atleast I'd hope so..
7. Apps that will ultimately benefit you are things like GO SMS Pro ( since the stock messaging constantly lags and freezes), Astro file manager, Androidzip, LTE On and Off in order to make sure your always using your 4G data only. And of course Uninstaller by rhythm software, Poynt one of the best find anything anywhere app and definitely Documents to Go from which I'm typing on now.
8. Sounds and keyboard is up next. Many like to use haptic feedback or sounds when you click things or type. However, use one or the other it may drain a bit of battery but its not a killer. Whatever floats your boat in that one but as far sounds go try and use either sound notifications or vibrate not both at the same time. Disable all LED notifications and allow yourself the satisfaction of being free of the annoying blinking light.
9. Charging the battery. Who would have thought that it would be important, but yea fools it is. The best way is to let your battery drain down to 5%, restart, then go for a full charge. But once that green light shows up you need to unplug it or else the battery gets angry at you and will decrease the power of the charge and ultimately ruin your battery faster.
10. As far as using different themes and wallpapers it honestly doesnt matter just stay away from the live wallpapers. We all know that touching the pond and making it seem like we just threw a rock in the water can be amusing but completely pointless. It has been reported that gingerbread is coming in Q3 of this year either this month or next, but we all know that could be bs.
When all said and done you will love the improvements and the fact that you didn't have to root your phone will put your mind at ease. I just wanted to share my knowledge of this phone to others to show and prove the fact that this phone is capable you just need to be proactive. Android is a perfect OS for smartphones, Linux like qualities, and strong structures that could really last. Any questions or concerns you can always message me. I just hope some one reads this and actually tries what I have successfully configured.

Save your pennies and buy an extended battery. No question. Bought one two days ago. Never even come close to this on any ROM. Finally I no longer have to carry a charger in my pocket.

Don't get me wrong. I appreciate the effort but there are so many threads that say the same thing.
The methods are not new. There are countless videos on YouTube that say this.
In theory if you're on XDA, you know a thing or two about kernels. I can get a full twelve hours on my standard battery with the right kernel with moderate use and nothing turned off.
If people want a phone to last for days, they're being ridiculous. That's why they have home and car chargers.

tl;dr
But according to other posts, I'm guessing it is about battery life...
As stated before, get the extended OEM 2750, I constantly pull 40+ hours out of it.

Everyone has their own version so your right its just repetition but it seems like others need a reminder. On my stock battery I can get 32 hours outta this phone. For IT guys like me its what I need from a phone like this.

OP's rant has all been said before (maybe not in one post) and will be said again before the last Thunderbolt user leaves the forum. I guess it needs said every so often so someone doesn't forget, I suppose.

Point 9 is completely wrong. Lithium polymer batteries are nothing like nickel-cadmium batteries, and neither is the charging method. Li-on and Li-po batteries are NEVER trickle charged in an HTC device, or any device for that matter, unless they have been user-modified. It's also completely impossible to over-charge virtually all Li-on batteries because internal circuitry prevents this. An overcharged Li-on presents and extreme explosion hazard. The act over attempting to overcharge one presents an even greater risk of explosion because as the battery reaches capacity the heat generated inside the cells ramps up sharply. Some charge techniques actually use this sudden ramp up in temperature to determine a fully charged state, that's how precise it can be. But HTC devices, and cell phones in general, do not use this technique. Instead, they take advantage of another characteristic of the battery. As the battery charges, it's voltage output and resistance increase. At the fully charged point, the resistance increases sharply and this tends to be less dependent on cell temperature which makes this method more reliable. Upon reaching this point, charge current is shut off, not reduced. Charge is allowed to bleed off through discharge down to 90-95% before charge current is again applied. The only thing that really reduces the life of a battery, defined as reducing it's number of charge cycles, is storing the battery with a full or empty charge. A Li-on battery can be stored for very lengthy periods with roughly a third of a charge though.

I've jus liked the xda forums a lot cus it seemed everyone would be mature n want ideas to keep flowing. Jus tryin to help, a phone like this can't be fixed in one paragraph I thought we all knew that.

I think it's good to know what others do to save battery life, especially on this phone. Only problem that I have is having to limit features of the phone. For example, why have such a big beautiful screen when you have to keep it dim to save juice? I'm not a fan of having to cripple your phone to get a days use out of it.
But +1 to the op for the advice. Always interested in other people's setup.

Keep this topic on track everyone, bans will be issued from now on for flaming, off topic garbage posted no exceptions

I bought the TBolt for its ability. Turning off all that ability seems counterproductive to me. So instead of turning everything off, I carry 2 extra batteries when needed. I get 5-6 hours of use out of my phone, flip batteries and continue on. No extended battery fat azz, no being tied to a charger. By the time 1 dies, the other is charged and another just in case. Works out well.
to each their own.

While I certainly applaud and respect the OP's position, I refuse to neuter this phone by turning everything off and making it a dumb phone.
I chose this phone due to the speed and features....turning off that just seems backwards.
Battery technology needs to make a jump, it's the hold up.
These phones should have 3000mah and NOT have a fat, rounded hump on back.
sink it into the phone..
The only thing I turn on and off with a widget is bluetooth.
I don't have the time to toggle between 3/4G, turn GPS on/off, etc.

+1 on this. He is absolutely correct on this point. Anyone who is into RC anything that uses Lipo's knows this as well.
The reason Toyota does not use Lipo batteries in their Prius' (even through they pack more power in a smaller package) is because of the extreme fire hazard from overheating lipo batteries by trying to "overcharge" them. They are afraid people will try and modify the charging systems to "squeeze" more juice out of them and catch fire.

I still don't see how its possible to get 40+ hours even with the extended battery. I'll be lucky to get 24. I do use my phone heavily tho so that may be why idk -.-

Dummy’s Guide to Improve Battery Life of your Smartphone

No matter which phone you have, an iPhone or a GS3/GS2 or a Xperia device, you always fret over the battery life of your device! (Xperia owners a little more)
Instead of splashing out on expensive battery packs, here is a list of things you can do to get the maximum out of your battery :
1. It’s all about the Apps!
Many of the more than one million apps available to download to smartphones contain programming errors and software bugs that mishandle power control. This means your devices can remain active when they should be sleeping which further leads to unnecessary draining of your battery. Identify these apps! (Other apps like Carat can help you with that) and monitor there use!
Also, there is a good chance that there are apps running in the background of your phone that you think you closed or reappear each time you reboot your device. Fortunately, it’s easy to identify and correct this on the iOS and Android operating systems with a few easy steps. All open apps drain battery, so in this case, the lesser, the merrier!
2. The battery is always better on the cooler side!
Your smartphone most likely uses a Lithium Ion (Li-ion) battery. Be aware that extreme temperatures can negatively impact battery life so whenever possible keep your device in elements between 32 and 95 degrees Fahrenheit. While a frigid phone should reclaim its functionality once it returns to room temperature, an overheated device could permanently ruin your battery. Over the course of a year, prolonged exposure to climates above 95 degrees could reduce a phone capacity by as much as 35 percent.
Remove any protective cover or accessory every time your phone is being charged. When you’re walking around, keep your phone in a ventilated holster or belt clip rather than a sweaty hand or pocket. Over-charging will also contribute to an overheated phone.
3. Always look at the bright side of life! – well the screen actually!
Turn on Auto Brightness! Most phones have an ambient light sensor that adjusts the brightness of the screen based on the light around it (darker in dark places, brighter when there’s more ambient light) to both save battery and make it easier to see. Turn Auto-Brightness on and you’ll save battery because your screen will need to use less power in dark places.
If not, manually adjust your screen brightness according to your needs by accessing it from the settings menu.
4. Stay (dis)connected!
Transmitting data wirelessly takes battery and leaving Bluetooth on to accept incoming data at all times requires even more juice. Turn off Bluetooth except when you’re using it (duh!) to squeeze more juice from your battery.
3G can be a real battery zapper, especially if you’re using it in an area of marginal coverage. If in doubt, your phone probably has a toggle setting where you can set your phone to use only 2G, You will soon see an extension to battery life that way while not really compromising speed or service.
And disabling a 3G connection when not needed is just the start. If you know you’re going to be away from home or a known wireless Internet connection, turn off your Wi-Fi locator. Also, GPS is particularly handy if you find yourself navigating somewhere new, but don’t leave it on all the time if you’re not using it.
5. Zip it!
When in a meeting or a movie, switch your phone into silent mode. Unnecessary notifications will only lead to lesser battery life. Use a basic ringtone! Advanced ringtones can sound better, but the phone will die soon! Also, turning off location services and push-notifications is definitively a step-forward towards saving battery life!
If you discover your smartphone seems to be running out of battery life quicker than ever despite your habits remaining unchanged, it could be worth investing in a spare or new battery. It’s worth noting that aftermarket batteries not made by the original equipment manufacturers (OEMs) are considerably cheaper. They do, however, vary in quality. Some aftermarket batteries can be trusted, but be aware of ‘too good to be true’ prices for smartphone batteries on retailers like eBay. You could end up with junk, or worse, a faulty battery that permanently damage your device. Buy carefully and smartly from trusted retailers to be safe.

Underclock your phone to 800/1000Mhz (while you are travelling) cz SGSII can do most of the stuffs within that speed.
Use Custom kernel like siyah wch has better battery backup than stock
dont set min freq to 100MHz cz 200MHz is much more energy efficient than 100 & has more operationg power !!

Come on man, show some love for Celsius! Besides, it is what most of the world uses and is not seemingly arbitrary (or based on how cold it gets in the average american's basement)!
Anyway, well written guide, may prove useful for the lesser knowledgeable folks out there

Whilst I applaud you for putting this info together, it is not specific to the SGS2. This is SGS2 General. This kind of thread belongs General Discussion or at the very least in Android General (tho probably the former).

For 1. I would recommend using an app such as Go Power Master, as it tracks which apps are running as how much power they are using. Some apps are always running, but use very little power while others can use a lot while it is running.

Also, if this may be applicable:
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors (as mentioned above), and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on. As far as power cycling, I run my Atrix 2 in performance mode all the time, and with a CPU overclock of 1.25GHz and various tweaks, I have about a day an a half to a day and a quarter of full runtime from my battery. This is moderate to heavy usage (calls, emailing, text, gaming, web browsing, etc.) so you should have no problems getting acceptable battery performance after following these steps:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

Actually I underclock my GS2 to 800Mhz thanks to an AOKP Rom and my battery last one hour or one hour and a half more, which is great when you just have 7/8 hours of battery life normally. It didn't really affect the use of common apps, but of course if you want to play big 3D games, I suggest you to clock it a its original rate (1.2Ghz for the GS2 for example).

This is bump charging and while it does work, it is not good for Li-on batteries. I'll find the link and edit it back in but bump charging will shorten the life of your battery due to inconsistent charge cycles.

This is from my battery guide. OP (or anyone for that matter), feel free to check it out. There is far more information, apps, deep memory management trick,... Link is in my signature.

**Note that this can be done two other ways. You can boot into CWR or Custom Recovery and go to Advanced Settings and there will be the Wipe Batterystats.bin option. Or you can do it manually by going into /data/system/ and deleting the batterystats.bin in there. Any of the three methods work to get the entirely same result in the end. I just like using the app or manually myself. **
<Snip>
Recently there has been information debunking this process. I will post it below, however I know what it says, but I also know what I've seen/experienced too. Here is the post by Dianne Hackborn, a Google Dev on her G+ account.
Dianne Hackborn - Jan 12, 2012 - Public
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

The point of doing so is if you happen to get incorrect battery reporting, which DOES occur in certain capacities. So, in my book as well as many others, it does matter for these situations. If only one developer told you the world was flat, would you believe that also?

Battery stats has nothing to do with battery reporting. And it was an engineer from Google's Android team that debunked the battery stats wives' tale.
So yeah, folks probably should believe a recognized subject matter expert when they clearly and concisely debunk misinformation such as the advice to wipe battery stats.
Also, it bears mentioning that the os clears battery stats upon every reboot, making the advice to do so even more pointless than it already is.
