12.2.1. Phone Cases
Keeping your phone protected from damage should be pretty important to you. The
phone case that come along with your phone can effectively mitigate your concerns.
OPPO original phone case is made of TPU material, which is lightweight and soft,
and helps keep the original 'feel' of the phone, since the case is a tight-fitting overlay.
It does a good job of protecting against drops and shock damage on the corners and
rear of your phone, also can reduce the damage caused by extreme temperature,
liquid and dust invasion, etc.
12.2.2. Screen Protector
OPPO provides you with an original HD clear screen protector made of PET material,
which is a thin piece of electro-conductive film that self-adheres to your screen. It
protects your screen from cracking, also does offer resistance to scratches, finger
prints and abrasions. Besides, OPPO screen protector ensures high-definition and
sensitiveness of the screen, which will not affect the screen display quality.
12.2.3. Maximize battery life and
lifespan
Note: Rechargeable batteries have a limited number of charge cycles and may
eventually need to be replaced. It is normal for the battery to lose its capacity over
time, but you can do the following to maximize its life and lifespan.
Use OPPO original accessories. Charge the phone with OPPO original power
adapter and USB cable. Charging with third-party charger accessories might impact
battery lifespan or even cause security incidents.
Use at a suitable temperature. OPPO smartphone battery is designed to have a
good performance in a wide range of ambient temperatures, with 16° C to 25° C as
the ideal comfort zone. When temperature is higher than 45°C, battery capacity will
damage irreversibly, and phone might even short-circuit and burn.
Do not use when charging. Programs such as long-time calls, games or online
videos will make phone get warm quickly.
