1) Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a device is mainly cause by heat rather than charge / discharge patterns.
2) Batteries with fuel gauge should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
3) Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
4) Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
5) If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

7.Run the device’s battery down until it turns itself off.
8.Turn the device on and charge for at least 8 hours.
9.Unplug the device, turn off, then charge for another hour.

Wakelocks?

etterBatteryStats to check what is keeping your phone Awake and not allowing the phone to enter deep sleep
In the words of the developer:
I wrote BetterBatteryStats because I was missing the great battery history that Spare Parts allowed to call on Froyo:
- Process stats with User and System CPU time
- Network Usage with bytes sent and received
- Wakelock stats (the most important one when it comes to battery drain)
This app is still under development and may contain bugs. If you find one you can keep it, but I’d be happy if you could also report it to me. BetterBatteryStats is calling the “batteryinfo” service of Android to retrieve data already lying there without generating overhead. BetterBatteryStats is focussing and has been tested on Froyo and Gingerbread and the APK is set to run only on those versions only.
What are wakelocks and why should you care about them?
When it comes to Android the most discussed and commented topic that I know is battery drain / battery life. I’m a quite heavy user because I spend a lot of time on the train every day reading my mails, surfing and listening to music but still my phone is off for a long time during the day and while I accept the battery being drained while I use the phone I care about it draining slowly while “doing nothing”.
And here’s the point: my SGS2 drains about 2-10 mAh where it was up at 20-100 mAh before I started cleaning stuff up.
Phone not detected by PC? Installing KIES did not help?

How do I enable my phone to connect to Kies?
Disable USB debugging
Setting > Applications > Development > untick Enable USB Debugging
KIES is often reported to be unreliable especially on Win 7 systems. You do not need KIES to have phone detected by PC> Install KIES if you need to sync data ( eg contacts, address, music etc ) with phone.

Navigation in Google Maps?
» Click to show Spoiler - click again to hide... «
Basically, you just need to replace the map data : see tutorial here :
http://forum.xda-developers.com/showthread.php?t=1007132Tips from user selphy :
Ok, for those of you who have trouble installing the Google Maps (for Navigation), i had issues too, but managed to do it through the following:
1. First, make sure your phone is rooted, then download the Google Maps-ownhere.apk (NOT the re-sign one), and transfer to your external SD card.
2. Using Titanium backup on your phone, wipe data and then uninstall both Google Maps and Street View.
3. Then using root explorer on your phone (i used Super Manager, which also has root functions), transfer the Google Maps-ownhere.apk file to your phone's system/app folder (make sure its set to R/W).
4. Then just reset the phone, and voila! Navigation is available!
Data Usage?
» Click to show Spoiler - click again to hide... «
Popular applications to monitor data usage is LBE Privacy Guard and Onavo. 3G Watchdog/3G Watchdog Pro is known to be not so accurate so I advice users to use Onavo or LBE Privacy Guard as it is free and Reliable.
Titanium Backup?

Titanium Backup is the best app to backup your apps, there is 2 version available, Free and Pro.
Difference between the two apps
Features of the Free version:

Very fast app listing (~1 second for 300 apps)
Sort apps by name / last backup / backup frequency
Filter apps by name / type / status / Apps Organizer labels (also affects Batch operations)
Backup/restore regular apps + their settings
Backup/restore protected apps + their settings
Backup/restore system settings (incl. Wi-Fi AP list)
Restores the Market links when restoring apps
Zero-click background batch backup
Interactive batch restore

Zero-click app un-installer
Zero-click system app un-installer
Desktop widgets
A single weekly or biweekly scheduled backup
User-defined apps lists with filtering, coloring and scheduling support
Additional features of the PRO/Donate version:
Multiple backups per app (history length can be chosen)
Zero-click background batch restore
Encryption of your backups (asymmetric crypto: the passphrase is needed on restore only)
Batch verification of all backups
Ultra fast HyperShell (much faster for almost everything)
Market Doctor can remake any broken Market links (only for apps that were backed up with the link in place)
App freezer can disable an app (and make it invisible) without un-installing it
Batch app freezing/defrosting
Unlimited, independent scheduled backups (each of which can run 1 to 7 times a week)
Dalvik cache cleaner can free up precious internal memory
Integrate updated system apps directly into your ROM to free up even more internal memory
Synchronize all (or some of) your backups to Dropbox
Retrieve all your backups from Dropbox (in case of lost phone or SD card failure)
Brand the app with your name
Nandroid or Titanium?
» Click to show Spoiler - click again to hide... «
First of all , Nandroid Backup is NOT an app. You will have an option of a FULL backup of your phone as it is condition at time of backup using a BACKUP choice in ClockworkMod recovery. Your backup here is often called a Nandroid backup . All your phone's data, apps, settings, roms, kernel etc is FULLY 100 % backup, Under this ClockworkMod recovery you will also have option to RESTORE 100 % the phone status
Titanium Backup is an APP which requires phone to be rooted. You can use TB to backup all your apps and its associated data. You ONLY can use TB in a working phone . You can restore anything from TB if your phone crashes and cannot be rebooted. TB does not backup your kernel/roms,

. You read it from the internet? I've heard of that before about lithium batteries, but didnt know that the smartphone is using lithium batteries.
Normal usage for whole day from 8-6 i still got around 50% left with constant checking on fb throughout the day. If normal not busy day with a lot of break in between classes, then I need charger with me. Gaming sucks battery.
