n95..battery life..

Re: n95..battery life..

Saving power is the key here. I know the battery is too weak for this phone but the n70 had the same problem.

1.Switch to gsm (only) instead of dual mode. This will save loads of juice.
2.Turn off wlan scan.
3. Use a profile without vibration (this may be hard for some ;-) )
4. Don't use full contrast and brightness
5. Don't use apps with automatic gprs/3g/gps/bluetooth/wlan use.
6. Keep bluetooth off when not in use.

Use options above only when needed, this will save a lot of power.
I know it's only a way around but no alternatives yet i believe.

Ps: E90 has about all the specs of n95 (less at some respects and more on others) and comes with a 1500 mh bat.. Enough juice here. Just a bit heavier!!

Re: n95..battery life..

oh and i forgot,

Wait before charging for the batt to be almost completely dead on a regular base.
This will flex the batt for better use. A battery charged often when still half full gets lazy.

barte90,

This is BAD advice
LITHIUM ION BATTERIES DO NOT GET LAZY AND DO NOT HAVE MEMORY EFFECTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Just charge them as often as you can and keep them topped up!
Do not-
Condition
Discharge
Cycle
Lithium Ion batteries do not need this and in fact you can decrease their capacity by doing it!

bikegrit, what's bikegrit?
Read these for your info, but, especially read parttwo-37 regarding mobile phone batteries. Keep an open mind and learn a little each day!

Re: Better battery or no more Nokia phones!!

Nokia will have big problem in their hand if they don't come with some solution of extending battery life!! This is my first nokia phone for years after using just Sony Ericsson with at least 3 days battery life and I did big mistake purchasing Nokia N95. If Nokia do not come up with better battery for N95 there will be many customers who won't buy Nokia products after this.

Re: n95..battery life..

I've got to agree with pa49, but chill out a little dude not everbody has your knowlege.
Here's some info from Wikipedia:

Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a longer time, they should be brought to a charge level of around 40%. Lithium-ion batteries should never be "deep-cycled" like Ni-Cd batteries.
Lithium-ion batteries should never be depleted to below their minimum voltage, 2.4v to 3.0v.
Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly.
According to one book, lithium-ion batteries should not be frozen (should not be stored below -40 °C), because most lithium-ion battery electrolytes freeze at approximately −40 °C (this is much colder than the lowest temperature reached by household freezers, however).
Li-ion batteries should be bought only when needed, because the aging process begins as soon as the battery is manufactured.
When using a notebook computer running from fixed line power over extended periods, the battery should be removed and stored in a cool place so that it is not affected by the heat produced by the computer.

Re: n95..battery life..

I don't know whether this will help anyone but I had many similar troubles with battery life. With wireless scanning off, 3G on, bluetooth only as required, I would get about 24 hours "on-time"...and I would consider myself a very light user.

Then, about a week ago, I purchased a spare battery and a desk charger to charge both the phone and spare battery simultaneously and found that the battery charged 'outside the phone' is lasting me significantly longer. I have run a test over the last few days on both batteries and found they perform the same as each other, so it was not that the new battery is better.

The net result is that, at this moment, I have my original battery in the phone. I have listened to a few tunes, taken & backed-up a few photos, synchronised with Outlook a few times and my power meter is still showing 'full' with the phone being left on continuosly from 12.00 pm Saturday (just over 49 hours ago).

Maybe the Nokia phone itself is stopping the charge cycle too soon...I don't know, I'm certainly no battery expert. That said, I thought this may be useful knowledge to pass on to some of you here.

Re: n95..battery life..

Actually, something else that may be relevent just occured to me (have no idea why this never occured to me!) but the "Desktop charger" I puchased was basically a stand into which you plug your mains charger so, for convenience sake, I purchased a new charger which was a Nokia-compatible one so I've been using that rather than the one that comes with the phone. Here are the two pieces of equipment:

Hope this works for you guys and gals!

Re: n95..battery life..

After 10seconds research I found this:

It is important to learn battery care information for Lithium-ion batteries to enhance the performance and extend the useful life of the battery. Because they are the newest technology batteries, they offer several advantages over NiMH and NiCd batteries. Lithium-ion batteries are preferred for their lighter weight and higher performance. Lithium-ion batteries are typically 20-35% lighter and will provide 10-20% better performance than a NiMH battery of equivalent mAh rating. Lithium-ion batteries are also unique in that they are not susceptible to the "memory effect".

A new Lithium-ion battery will benefit from an initial "conditioning" of the battery. For the first 3 charge cycles, fully charge the battery overnight and allow it to fully discharge before recharging. Once conditioned, Lithium-ion batteries will perform best when charged at a rate somewhere between a conventional slow charge and a rapid charge. When rapid charging, Lithium-ion batteries require a charger designed to charge Lithium batteries. To achieve a true full charge when rapid charging, the battery needs to be slow charged the last 10-15% of its charge cycle. Most "intelligent" desktop and Lithium-battery rapid chargers provide this capability. A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours).

So it appears that it is better to "condition" these batteries first off!!!
