You will be unable to update if you are on custom rom.

He is giving you GOOD advise not to use ahem apps
I fully support his views
I paid for ALL my apps and I always say I have never any issues of sudden freezing, hangups in ALL my android phones I have used to date. Unlike many users here who always complain of apps crashing, phone freezing due to most probably bad combination of ahem apps
Developers do need our support. If most users start using ahem apps, they will stop developing
End result we users will not benefit
Android apps generally are cheap US 0.00 to US$3
No one can force you not to use such ahem apps . Only your conscience can advise you
To me using such apps is equally similarly to stealing intellectual property - you are no better than those petty thiefs

I am surprised at your question since you are a EXPERIENCED android user having use other androids before
How much battery % can you expect to lose in your scenario, no need to ask you should already know
If you wake up and your battery near empty than i suggest you throw your phone away as it is hopeless
In your stated scenario, my 3G always on and active 3 email accounts download, newsfeed, facebook notifications active battery drop is most 5-6 % only over , say 8-10 hours

My Sandisk 64 GB class 10 : actual speeds - write 11 mb/s while read is ONLY 19 mb/s

You do a nandroid backup easily from Clockworkmod Recovery. Boot phone to recovery mode and just select backup will do

Use titanium backup to backup apps n its data. And after factory reset install back titanium n restore
Choose external sdcard as titanium backup

Serves me well past 2 years
Make sure you buy original as plenty fakes especially in kl
Check their website how to distinguish between original n fakes

Odex ROMs have their main files moved to another area for faster booting while when you deodex the ROM these files are compiled back inside the APK....

To know whether your phone is Deodexed or Odex, just open Root Explorer app and navigate to "/system/app" and check if there files with ".odex" extension....
If yes then your ROM is Odex
Otherwise, your ROM is Deodexed....

The benefits of having a Odex ROM :
1. More space in "/data" partition.
2. First boot is faster.

The benefits of having a Deodex ROM :
1. You can customize the ROM the way you want without worrying about odexes....eg themes , changing status bars

suggest you send in phone to check k
have never encounter such issue even if phone still plugin when fully charged even for hours

It is very simple. Menu select extract from nandroid backup. You will see list of all apps backup n select all or what you want
Next time launch app yourself n find feature yourself instead of waiting n keep asking here.

That is because you never bother to explore the app features. Select the rightmost top pad logo n you have even more features

If you have done so you will know by just looking at menu
No need keep asking here
