Nokia 5800: How to solve low battery charge issue

Nokia 5800: How to solve low battery charge issue

It’s a good habit to make a battery reset about each 1-2 months, to calibrate it and get the most from your 5800.

Just follow these simple steps:

  1. Switch off the phone
  2. Full charge it
  3. Unplug the charger
  4. Take off the battery
  5. Wait about 10 minutes
  6. Insert the battery
  7. Plugin the charger

If the battery was not calibrated, you will notice that it can now recharge for some extra time (about half an hour in my case, and it means a LOT OF additional juice). You can repeat the process more times if needed, or if you simply want to check that it worked.

Don’t switch ON the phone during the whole operation, and be really careful not to damage battery pins during steps 4-6.

Additional tips

Here there are some additional tips for maximizing the battery life of your Nokia 5800:

  • In Settings->Phone->Display set to 50% the Light sensor, and Lighting timeout to 15 seconds. Sadly the screen is what consumes the most of the battery charge on your Nokia 5800.
  • In Settings->Phone->Lighting-alerts>Events notified uncheck all the entries and press ok.
  • In Settings->Connectivity->Network->Network mode select GSM mode (only if you never make video calls).
  • Don’t wait every time that phone is fully discharged before recharging it: lithium batteries doesn’t suffer of memory charge effects, so you’d better make many small charges rather than big ones (that you should do every 20 – 30 charges). This will also prevent excessive battery overheating.
  • Unplug the phone from the charger as soon as completely charged. Never let it charge overnight, for example. This would involve the aforementioned phenomenon of overheating.
  • Avoid to use the phone as an alarm clock. It seems obvious, but it is better to use a real alarm clock in order to not waste charge. If, however, you still want to use it as an alarm clock, and you intend to let it play several times during the morning, remember not to turn it off at night time but leave it in offline mode, in which the power consumption is very small. Keep in mind that the reboot is the process that consumes more battery juice.
  • Locks up the screen often, using the appropriate key, in order to avoid wasting energy.
  • Always kill unused applications.
  • Use headphones instead of speakers.
  • Turn off the camera flash when not necessary.
  • Minimize the use of Internet and wireless: they involve a great deal of power and may reduce battery life to a little more than an hour. The same considerations are true also for GPS and games, especially 3D ones.
  • Turn off Bluetooth when not in use.
  • Keep your phone operating system constantly updated, through the instrument “Software Update”, downloadable from the Nokia website.
  • Turn off the touchscreen vibration.


  1. Hi my mobile dropped in water and then the battery backup has declined.. what might be the reason for that? What should I do? Please help me..

  2. put it in dryer and if it still not works, put it on the railway track and then go for a new battery 🙂

  3. @Pandu: Dry it with a hair dryer an keep it out for a while… if the battery is still so bad you need to buy a new one…

  4. It worked for me! Thanks a lot!

  5. This is really a useful tip, and it makes sense. In the shop where I bought my nokia 5800 they told me to charge it 3 times for 12 hours each time. But my cell fully discharged overnight. I am following the procedure, I will report on the results. Thanks a lot!
