Follow-up question - my battery just died after only 18 months, and requires replacement. What can I do to extend the life of the replacement battery beyond 18 months?

The obvious: disable bluetooth and wifi unless you're using them. Disable 3G when you're not surfing the web or when you're near wifi anyway. (disabling 3G saves massive amounts of battery juice).
Screen brightness. THE big one. Learn how bright you really need it.
Widgets and homescreen shortcuts. Which ones do you really need? Every time you look at the screen to check the time, all those widgets and shortcut icons need to be rendered - that takes up to 50% of processing power!
Wallpaper... Go for all black. Or all white etc... crazy wallpapers need more power.

Background sync: Do you need push email/tweets? Is every 30 minutes not enough?
Vibrate: unless you're on jury duty, kill vibrate of all sorts! Big user!
Unnecessary apps & files on your phone: EVERY icon needs to be rendered all the time - whenever you open the app drawer, look at the homescreen... that takes power.
Their components, services, processes etc are always being indexed even if you never use them. Same goes for photos, videos and documents: they are indexed so a thumbnail is created when you open the gallery or document reader. How often do you look at the 500 lolcatz? Nope, thought so. But you may wanna look at the last photo you shot; but all those thumbnails of old pictures take processing power, RAM, battery juice.

Allbums and folders.... no longer just for neatfreaks. Putting songs and photos in folders or albums of 10-20 files doesn't just help you stay organised, it helps your phone (or PC/Mac) too... indexing, and rendering become easier, and what's easier uses less energy....

ACCOUNTS: if you have 10 email accounts, don't set them ALL up on your phone.
YOU can have gmail or yahoo (or most emails actually) to gather your mails from other accounts, or you can forward mails from one account to others, then YOU ONLY use that account on your phone that gathers all the mail. It still uses that same amount of data to download actual mail, BUT YOU ONLY POLL ONE account instead of 3, 5 or 10.
That is why Nokia's email client on Symbian was so damn efficient - all the mail goes to Nokia's servers. They poll and only send you actual mail.... Same goes for BB email...
You can get there if you use forwarding and email gathering...

SMS/MMS... instead of 10 sms, can you send one email? Much more efficient. Dito MMS - email is more efficient. If the recipient can get email, use email.

Apps that you do use a lot: always read comments in PlayStore before you update - it happensquite often that updated versions of apps add bugs accidentally, and RAM leakage and excessive battery use are very common. Wait for the impatient to vent their anger or give the thumbs-up when an app has been updated.
OR FORGET ALL THAT and get something like this extended battery

Very thorough
Check the battery stats to see which apps are using power and see if any are using more than they should. Check the awake line on the History details page to see if something is stopping it ever going into deep sleep.

Good advice from both of you. FWIW, this doesn't just apply to the Ace 2, it applies to pretty much every phone out there.

Also, disable Wi-Fi when you know you're not going to be near a wireless network, as it's constantly searching for one and wasting battery.
