Another testing. This morning I browse on HSDPA for about 5 min. The battery compartment is quite warm. More warm than I browse using the original 1050mAh.

I don't know why my battery is contradictory to all of you. The reasons I can think:
1) May need several discharge/charge cycle
2) Battery problem
3) My N82 problem
4) User problem

Thu - start using, discharge
Fri - first time full charge
Fri, Sat - discharge, 8pm = 4 bars.
Sun - still discharge. 12am = 3 bars.

I really hope after several cycle of discharge/charge, the performance will improve.

Try install Jbak Taskman (freeware) and look at all the apps and hidden-apps running in background. Try to close/kill all and try with Nokia Maps again. I do encounter Out of Memory from time to time and after reboot, the app works fine.

Take note N82 has:
[C:] 128MB ROM - install apps, etc. Also known as Phone Memory.
[D:] 128MB RAM - memory like PC RAM.
[E:] Memory Card - micro-SDHC

Out of Memory means C: or D:
Nothing to do with E: Memory Card, unless your memory card really runs of of disk space or has problem

Thanks for the offer. Let me try full discharge and charge several more times. The battery last till about 1pm (Sun) just now. Total about 51 hours. Then I do a 2nd full charge just now with the phone switched off. 3PM (Sun) I switch it on again. Now monitoring.

I repost the full details below. Daily usage:
1) Browse online using phone only about 10 minutes a day. Average can say 5 min on GSM (GPRS/EDGE), 5 min on UMTS (HSDPA 3.5G)
2) 20-30 SMS a day
3) Browse phone for fun, gallery, etc. about 10 minutes a day.
4) Connect to PC to install apps, move files, etc. about 5 minutes average
5) Daily calls about 10 minutes average.
6) Maxis line, always on GSM only.

As you can see above, is not really heavy usage. No music, no frequent flash/photos, no games nowadays. I mainly use it for calls, sms and online. For the past several months, I have switch back to use the default Nokia 2GB micro-SDHC card. Also, I am in same location, same signal strength/weakness, i.e. environment and the rest is similiar for testing comparison.

With the above usage (x2 for about 2 days usage), the original (Zitron) 1050mAh battery can last me about 40-50 hours average. That is a 1 yr old battery, which is charged 5-6 times a week for the past >12 months.

SunGlobal first discharge/charge cycle, the 1800mAh has the same performance of 51 hours. Based on my own mAh calculation with some allowance on lower grade material compared to Nokia OEM, I am expecting a 30-50% increase only. Not 71% increase [1800-1050]/1050 x 100%
Therefore, I am expecting a performance of at least 65-70 hours, give and take a bit.

Anyway, let me continue monitoring and will feedback here.

The puny Xenon flash on N82 and other digital camera is useless for distance >5m away. There is an article I read previously, you always see ppl in stadium, concert, etc. at night using flash to take pictures from TV (e.g. opening/closing ceremony). It is rather pointless to activate the flash.

Even with those external mounted flash on SLR/DSLR, it is only good up to maybe 10-30m only.

The proper way is to disable flash, enable night mode and have very steady hands. Also, preferably the subject is not moving.

To take proper pictures at night, the best is to use SLR/DSLR, where you can play with the aperture/f-stop (f2.8, f5.6, f11, etc), shutter-speed (1/30, 1/125 , 1/500 , etc.) and steady hands. You need to balance the aperture and shutter speed to take great picture.

N82 + Xenon is only good for near (<5m) pictures and preferably fixed objects at night. Same with other small/slim digital camera.

Sun 3pm [0 hrs] - Full charge
Mon 10am [19 hrs] - Drop 1 bar

Yes, you are right. I have posted (a few times) a link somewhere in N82 V4, 5, 6 thread. Lazy to search out again.

Update: 2nd full discharge update on my Sun Global 1800mAh battery.

Sun 3pm finish full charge
Tue 11am totally finish.

2nd discharge = 44 hours only

1st discharge = 51 hours

Results: Not good. Similiar performance like my original 1050mAh.

Need to install 3rd party applications. Google for Shake SMS.

Added on June 2, 2009, 2:59 pmN82 is like a traditional or more serious/business type of phone. N82 is a wrong choice if you are looking for a music phone. I strongly suggest to get 58000XM.

For gaming, movies, etc. N82 2.4" screen is not good, compared to others with 2.6", 2.8", etc.

To upgrade, you can do your own. PC with WinXP.
- Download Nokia Software Updater (NSU)
- Install
- Plug N82 (or any Nokia h/p) into PC using USB cable (better than BT)
- Run NSU and follow the instructions

Comparing within Nokia or Symbian S60v3, I would say N82 is one of the fastest around. Maybe N97 will be faster with 400MHz+

Camera wise, among h/p (not Japanese ones), it is one of the best. Problem is mostly due to hand shake or too high expectation from a simple point and shoot camera. I'm disappointed with N82 pictures also if compared to my pro-sumer camera.

To me, WiFi is not slow. It depends on the WiFi line is congested or not. However, to compare loading times with a laptop, is of course no match.

Your camera picture not deleted, I think something wrong with firmware, phone, memory card or something. Anyone encounter this ?

Games = no comment, depend on individual type of preference. I like simple games or brain/IQ games on h/p. Anything more complex, I play PS3.

Battery wise, is really a disappointment, whether original higher mAh. Last 1 week ? Get back the old N3310. No way a Nokia with 16M colours can last >3-4 days on average.

Some phones are just not for every type of person. Some may prefer multimedia phones like 5800XM. Some prefer sliding like N95. Some prefer cover flip-phones.

Some prefer SE, moto, LG, samsung, etc. phones, features, menu, etc.

For now, the only phone to upgrade for me is N97.

Yes. Where ?

Update: 3rd full discharge on my Sun Global 1800mAh battery.

Tue 1pm full charge
Thu 4pm full discharge

3rd discharge = 51 hours (note: less usage than previous)

Results: still same. not good.

2nd discharge = 44 hours only
1st discharge = 51 hours

WiFi is not that power hungry. The drainer is LCD constant on with backlight while you are browsing. I estimate constant on LCD (no hack brightness) will finish drain a fully charge battery in 3-5 hours.

1) How old is your battery ?
2) Authorised/AP set battery ?

Weird, you guys can last >70hrs+

Do you guys leave it on 24 hrs a day ? Or switch off sometimes ?

Maybe is the cause that eat up more battery ?
Mine is default brightness -> in the middle.

But anyhow, is the same settings to compare the 1050mAh and 1800mAh battery. My expectation is just 30-50% longer, not 80% longer. Somehow, it is just 1% longer

I saw at my area morning wet market. Got h/p accessories seller there where I used to buy the crystal case

Added on June 7, 2009, 8:54 pmYes, N82 GPS antenna is on top, i.e. at the back, above the camera.

The GSM antenna is at the bottom, somewhere behind the D-pad. WiFi antenna is also here.

Search for the GMXT map.

Added on June 7, 2009, 8:56 pmMy current new 1800mAh low battery 1 bar... last me 7 hrs. But of course, no calls and just 1-2 sms only.

Update: 4th full discharge on my Sun Global 1800mAh battery.

Thu 6pm full charge
Sun 7am - left 1 bar. Low battery warning.
Sun 2pm full discharge

4th discharge = 68 hours (note: even less usage than 3rd discharge)

3rd discharge = 51 hours (note: less usage than previous)
2nd discharge = 44 hours only
1st discharge = 51 hours

Comment: For new battery, the low-battery can last longer. With very low usage, seems like the battery can reach 60 hours. Need to monitor further.

Note: 99% on GSM (not UMTS)

1) Plug into PC as USB (not PC Suite). Preferably use USB card reader.
2) Do a scandisk and recovery (if possible)
3) Backup all and try to format in PC.

999) Claim the life-time warranty

N82 xenon flash still power !

Nokia N97 Q&A

How powerful is the flash? You have an N82, can you test them side by side? Could you say it's 50% as effective or... something else proportionate?

Dual LED is still only about 20% the brightness of Xenon for an average pub/club shot, and Xenon freezes action 100x better.

If after reset to factory default, WiFi also not working, can only mean:
1) Faulty WiFi or some board. Replace or claim warranty
2) User problem. Try ask friends or tech people to help troubleshoot and configure the WiFi. If still not working, refer #1.
3) No WiFi, cause is Nokla N82. Unlikely ?

Update: 5th full discharge on my Sun Global 1800mAh battery.

Sun 2pm full discharge
Tue 11pm - left 1 bar. Low battery warning.
Wed 4am full discharge

5th discharge = 62 hours (normal usage, but final 1 bar test to maximum ~6 hours)

4th discharge = 68 hours (note: even less usage than 3rd discharge)
3rd discharge = 51 hours (note: less usage than previous)
2nd discharge = 44 hours only
1st discharge = 51 hours
