It is best to avoid task killers such as Advanced Task Killer. Android is designed to automatically pre-load certain applications, even if you don’t load them yourself. If it starts to run low on memory, it will smartly unload the oldest running apps automatically.

Manually killing tasks will only mean they get loaded in memory again. Task killers can make the phone slow, laggy, or drain battery life more quickly.

Battery types
When choosing a battery there are three main types:

1) Replacement Batteries (Genuine / OEM) – OEM stands for Original Equipment Manufacturer and is the battery that the manufacturer has specifically produced for your device. This is normally the best option in terms of quality, time between charges and overall battery lifetime, but these batteries can be a little more expensive, so it depends on your priorities.

2) Replacement Batteries (Non-OEM / Generic) – Another cheaper option is generic or non-OEM batteries which are often mass produced in order to reduce their price. They can also provide longer battery life by having a higher mAh (see information below), so these can be a good alternative to OEM batteries if you want to save money. The quality can vary however, so we recommend that you read the reviews before buying. Another problem with generics is that they may make your device run hot and they can also void your warranty if your phone develops a fault. In general we would always recommend you buy a Genuine/OEM battery if you can afford to do so.

3) External Batteries– These are ideal if you’re going to be away from mains power for a period of time, such as camping, festivals and so on. The idea is that you charge the external battery pack (from the mains) and then charge the phone off that. Often external batteries will only last for one or two full charges, however very large packs (with a high mAh rating) are available if you’re going to be away for a longer time.

Understanding mAh
Before you buy, you should also check the mAh rating. This stands for milliamps delivered per hour rating and essentially tells you how long the battery will last before it needs recharging. A high end phone with a large screen may have a battery above 2500 mAh, whereas a mid-range model (with a smaller screen and less bulk), may only use a 1800 mAh battery. As mentioned above, sometimes generic batteries can have a higher rating than the genuine battery. For example, if your phone comes with a 2200 mAh battery, you can buy a 2400 mAh generic battery which should mean it will last longer between charges. As above, be careful with generics however.

You can always use your own image as a wallpaper. However, most phones also have a preset selection of wallpapers (or live images) that can be used anytime too.
