Battery Replacement in Düsseldorf
If your phone gives up in the afternoon even though you use it no differently than two years ago, the battery is due. A battery replacement is one of the cheaper repairs and makes the biggest difference in everyday life — for iPhone, Samsung and every other brand, without an appointment in Düsseldorf-Derendorf.

When you should have the battery replaced
- The battery level drops in jumps
- The device switches off even though it still shows some percent left
- It gets unusually warm while charging
- The back or the screen is bulging
- iOS says the battery needs service
Depending on how you use it, a phone battery lasts two to three years before you clearly notice the difference. That is not a defect but wear: every charge costs a little capacity. After around 500 to 1,000 full charge cycles, a battery is noticeably weaker than on the first day.
On iPhones you can check this yourself. In Settings under Battery you will find a percentage for battery health. If it is below 80 per cent, you will notice the difference immediately after a replacement. On Android devices the value is not visible everywhere, so what counts there is mainly what you notice in everyday use.
We usually replace a battery in 20 to 60 minutes — on an iPhone just as on Samsung, Google or Xiaomi. Your data stays untouched, because we do not touch the storage. We also replace batteries in iPads and tablets here in our own workshop.
If your screen lifts at one corner or the back bulges, the battery is swollen. Please stop charging the device and bring it in soon.

What you should know about battery replacement
How do I know it's time for a battery replacement?
There are three typical signs: the charge level drops in jumps, the device simply switches off in the cold, or it shuts down even though it still shows some percent. On iPhones you'll find a value for battery health in the settings under Battery. If it is below 80 percent, you will notice the difference immediately after a replacement.
How long does a battery replacement take?
For a phone, usually 20 to 60 minutes. You can wait while we do it instead of leaving the device with us. For a tablet, we tell you when you can pick it up as soon as you hand it in.
Will my data be kept during a battery replacement?
Yes. During a battery replacement we don't delete anything and we don't touch your storage. Making a backup beforehand is still a good habit, simply because something can theoretically go wrong whenever a device is opened.
My battery is swollen. What should I do?
Please stop charging the device and use it as little as possible. A swollen battery presses against the screen and housing from the inside and, in the worst case, can leak. Bring the device in soon; we remove the battery and dispose of it properly.
Does fast charging damage the battery?
Less than people often claim. What really wears a battery down is constant heat, for example charging your phone on the dashboard in summer or under your pillow. Normal fast charging with a suitable charger is not a big issue for the battery's lifespan.
