Recharging your battery over long period of time will decrease the performance of it.

If you're using DiGi prepaid, you can still use their data plan. Unlimited, RM15 per week. I'm using that, no problem. It's normal if they suck your credit the minute u switch on your cellular data and 3G.

one thing i really notice is that if you charge your phone when your battery % is above 20%, battery tends to drop faster...

if you charge when your battery is below 20%, your phone battery last longer...
so usually i drain my battery below 20% every night before i do a full charge.

My advice try to do charge cycle at least a week.
A charge cycle means using all of the battery’s power and charge it when you Iphone can't turn on.

It can keep you Battery stay long and better performance

10% idle in 10hours is NOT normal... mine drop 1 or 2% only... slept for 12hours i think, lol

just updated to 4.3.3 jb with redsnow rc16 with multigestures

just updated to 4.3.3 jb with redsnow rc16 with multigestures


usage mainly on wifi and games only

Not 10% idle in 1 hour lar.. 10% in 10 hour
10% in 10 hour also not normal.

^ yes i know, was a typo.. haha....

and still... 10% in 10hr NOT normal...
i sleep 12hrs only 1-2%

I can never get results that good, and I'm on 4.3.3. My battery is usually dead in 6 hours of usage. I have around 7 apps with push notifications on. 3G is always on never off. When I'm at home wifi is turned on always. I don't play many games, but there is a lot of chatting on meebo and whatsapp, plus a fair bit of photography using hipstamatic, camera+, etc, and also the Facebook app, twitter, and other apps. Is this normal?

^ 3G does suck lots of battery... why don't you try a day without 3G or EDGE ?

I'm also on wifi and whatsapp etc... all my social apps have push...

i tried mine without 3g and wifi, off all the background app, the battery also drop in 1% in 10 minutes. in that 10 minutes only check whatapps for 1 minute. but when i off 3g, ppl hardly to call me. when i on 3g back, back to normal

Bros, my new iphone 4 (3days) JB OS 4.2.1 only last 8 hours with 3g/wifi off, brightness at 30%, all background apps are off when idle, play game for less than an hour, phone call around 15minutes and other normal chatting apps. is this consider normal?
my battery drop 1% in ten minutes which i use to check whatsapps and smses only for 1-2 minute.

Well I might try it for a day but I won't be turning off my 3G anyhow since it's not a smartphone without Internet access right?

I forgot to mention I set my screen brightness to about 80%. How bight is your screen?

I'm just want to share my case and my opinion here on how am i fix the problem of battery drain...hopefully this helping other people as well

my phone is 3GS, previously when i fully charged before i went to sleep, in the morning when i wake usually will be around 60%...i keep convincing myself that this is because i JB and installed a lot of apps...

but after one day, i found out that my usage time and standby time is always the same, so i try to figure it out...the result is...some processes are keep running even though in locked screen....

i did some research and found out that many apps will causing that problem, but usually due to JB (as JB gave you more opportunities to download more apps). For my case, the culprit is SBsettings.

Once i uninstalled SBsettings, my battery life improved A LOT, what i mean a lot is really a lot~



You can see from the image, after 13 hours of standby time + 49 mins of usage drop only 7%

Here are some of my settings:

MOdel: Iphone 3GS
Firmware: 4.2.1
JB: YEs
Notifications: ON (but for only facebook and any other social networking apps, the other apps OFF manually)
Brightness: 50% (auto-brightness ON)
Location: OFF
Wifi: ON 24/7
3G: OFF (because not signing up any data plan)

I rather sacrifice SBsettings than sacrifice my battery, so for those who are facing battery drain problem...you will need to find out the culprit...otherwise you will need to sacrifice your battery life and your time to charge once everyday~

@RynN - I have the opposite case as yours. Currently using iP4 and just started JB not long ago. Before JB, I lost about 10% per 8hrs (I charged my phone every night before I went to bed), usually will left 90% in the morning.

But after JB and tweak the phone with Cydia apps, I only spend 3% battery over the 8 hours. Currently I have:

- SBSetting (FREE)
- Lockinfo ($7.99)
- QuickDo ($7.99
- iScheduler ($7.99)

installed. SBSetting helps the most in my case, I can free up the memory, kill unsure background process, turn off WiFi when my screen is locked & etc. Beside that, iScheduler is my secondary power saver too. I can set my phone to automatically turn on / off functions like edge, 3g, wifi or any related process at the specified time. I bought all the apps mentioned, it might sounds a lil pricy but for long term I think it worth.

I am on 4.3.3 for my 16GB iPhone 4, Jailbroken with tons of Cydia Apps and SBSettings will be the first Cydia apps I installed (Can't have my iPhone without SBSettings)

I have Wifi on ALL the time. I switch on Edge and 3G only when I need it (that's why I have SBSettings so that I can switch them off/on easily)

BT is OFF only when I am using Celeste which is rare.

Notifications is ON but not for FB etc .... I don't even know what's the use of these stuffs anyway

Location services is ON

I usually get 2 FULL days of battery and if I don't use it that much to surf the net, I get 2.5 days before the battery dies on me.

If I switch on 3G/EDGE, the battery depletes 2% every hour (without doing anything)

@RynN - Yea. I maximized my phone power saving cause I need it when I'm on site, cause there is no way for me to charge if it dead suddenly.

Btw, you had just against the forum rules. No piracy is allowed here, pray hard David dont cross this thread else you will got free vacation. I bought all my apps officially from the dev as the sign of appreciate their works and time for creating such a wonderful tweak.

Hi all. Using IP4 here and 4.3.3 OS. Battery life is pretty ok - no major complains.

However, want to ask if there are any recommended Portable Batteries to get. Apple store sells Kensington & Griffin brands and I saw another one called iPower by Momax in a local store. Has anyone use them and if so, which would be the best value for money portable battery to get.

now i`m use IOS 4.1 , how to update be 4.3.3 ? i dunno how to do that n worry all my data like contact will be lost..
n after update 4.3.3 , need do jb back right?
